- In this video we react molten sodium bisulfate and potassium nitrate, in a reaction that i've done at least 14 times before over the years, what could possibly go wrong :)
/ explosionsandfire
The distillation is essentially the same as using conc sulfuric acid and a nitrate salt to obtain RFNA, but molten sodium bisulfate is used, which requires the pot temperature of the distillation to be just over 300 degrees.

Hey, want some advice about this?
I need a better username always yeah, hit me
1. Keep that distillation away from the sun, light catalyzes HNO3 decomposition, especially when gaseous.
2. Put some sodium persulfate in receiver flask, it will ox. NOx to extra HNO3 and absorb water contamination (you'll have to redistill but it will make high quality WFNA, maybe even with some N2O5)
3. Place the receiver flask straight vertically and put a piece of PTFE tube on receiving adapter so it dips into distilled acid.
4. Keep the receiving flask cool (wet rags and a fan should cool it enough by evaporation)
5. You can prevent suckback by putting a narrow strip of paper under the cork (place it vertically) after you stop heating this will make the system non-airtight.
6. Sodium potassium nitrate eutectic has a melting point of only 220 C.
www.archimedesolarenergy.it/images/molten/molten1.gif
It's prepared by mixing 55g KNO3 and 45g NaNO3, heating in a pot until fully liquid, cooling and pulverizing it.
(if you stir rapidly while it's cooling it forms nice lumps)
Also, have you tried asking for battery acid at a car repair shop?
Reply if you have any questions or comments.
I need a better username I've pinned this comment because these are all very good points. The best improvement definitely would be to put the receiver flask on ice and keep it cool.
The sunlight is definitely a factor too, it's easy to cover it up with some foil. Given the amount of NOx that comes over from the distillation anyway, I wonder if you're really helping, like you might make 5% less NOx, but yeah no effort to cover it up.
Very interesting thought about the persulfate. I usually use Urea to clear up my RFNA but I do have lots of ammonium persulfate I bought years ago that I don't often use, so I'll look into that!
I need a better username I have 3L of 50% sulfuric so I'm set in that regard. Years ago I did ask and they actually did give me about 800ml of 30% sulphuric, which I concentrated. Years ago though, a lot has changed since then and I look a lot less cute and harmless now than I did haha
Not sure making a nitrate eutectic will help a lot, it's an interesting thought. A bisulfate eutectic would probably work though, I feel that if the acid (bisulfate) is molten without the nitrate melting, it might work. But you could be right. Lowering the temperature would be a drastic improvement to the method
I keep watching your videos hoping one of your experiments will actually work.
Your parents probably still look at you with the same inspiration
@@n0username0n I think they are amused now days.
@@n0username0n the great thing about these videos is seeing the stuff that doesn't work. Much more real than a lot of other channels that never show what happens in real life.
@n0username0n Your parents probably look at you and wonder why you need to insult others to feel better about yourself.
Conc. sulfuric in Austria is also extremely expensive. In Germany I can get 96-98% for 14 euros/liter. Nitrate salts are unobtainable here. Even fertilisers which you can obtain don't contain nitrate salts you could use.
Even Methanol isn't allowed because of its toxicity.
Hobby chemistry is very restricted here sadly.
Yes, it is a shame that this has happened. I fear much of the world will follow Austria's example in the coming years
Or you have to get your chemicals from Poland / czech republic, wich is also very risky because of the police on the borders... I know your struggle and I feel exactly the same :(
Yes a lot has changed very quickly, the modern world is becoming so shaped by our fear of terrorism. It changes public perception too, so yes you do end up feeling like a criminal when you're not even doing anything wrong
I have a shipment of chemicals from Poland on the way! I few odd things, including the most expensive chemical i've bought, both in terms of total money spent and price per gram... i'm excited!
Drakkar Calethiel doesn't shop.es-drei.de or apcpure.com ship to Austria?
NurdRage's video points out that using sodium bisulfate monohydrate lets the reaction happen at the boiling point of HNO3 (83C) since the sodium bisulfate monohydrate can decompose at around 55C. Alternatively you can add 1 mol of water to the reaction.
Shading the receiving flask would be a good idea, light also causes nitric acid to decompose and you were working in direct sunlight.
TheBackyardChemist that's a good thought. I'm not sure how much it would actually decompose, but it hardly takes any effort to wrap some aluminium foil around the flask and avoid the issue completely yeah
bubble the nitrogen dioxide into hydrogen peroxide for better conversion to nitric acid
Remembers me that one time I needed anhydrous, gaseous hydrochloric acid for an experiment. We had a cylinder of it, but getting access to it was such a paperwork nightmare with Health&Safety, I just ended up making it myself with NaCl and sulfuric acid. (Whether this is any safer is... questionable, but it required no paperwork...)
The setup was something I could seal and completely put under vacuum, to make it air-free. So, of course, I needed a schlenk line bubbler to release any overpressure. Its exhaust was connected to a rubber hose that went straight to the top of my fumehood.
The rubber disintegrated. A little after the experiment, it got torn under its own weight, and would simply crumble in my hands...
piranha031091 yeah rubber does not like acid vapours. In fact most stuff doesn't like acid vapours... So the Teflon tubing is good in that regard, but only that regard
@@ExtractionsAndIre I know a few washed up hippies that would disagree with that point.
Thank you for this video. Its nice to have an inexpensive method for making nitric acid. I can order kno3 in bulk and nahso4 also in bulk.
Alternative to bisulfate you can use Manganesesulfate the nitrate manganesesulfate mix decompuses at 150C. The MnO2 has somewhat stabilizing effect on the NO2. Kuhlmann made so around 1850 his nitric acid with 1,42 destiny.
If you dissolved the two powders in in a calculated amount of H2O, wouldn't you distill over azeotropic (67%) Nitric Acid?
I haven't actually tried but, I think so. It theoretically checks out
Hi mate, good to see you posting again. Also check around your area as where there is mo-flo there is usually cheaper options. As I buy 5 liters of 98.4% H2S04 clear at $58.99 inc gst from another shop for the same purpose
Ps. Good use of the parafilm :^)
Jeff Harold Good to see you around still too mate! I'm always keeping an eye out yeah. For sulfuric, I managed to source some 50% acid through a friend for a couple dollars per litre, I just have to distill it which is a bit of a pain.
And yes, nothing else can seal the Teflon tubes like that except the parrafilm! Tape doesn't stick, so it's perfect! Appreciate it mate
This is a really good year for us amateur chemists! First NurdRage makes a video on how to make Sodium without having to melt NaOH, or NaCl for that matter. And now this! Fuming nitric from readily available chemicals. This is especially good for us poor nerds living under the tyranny of EU regulations. You can't buy nitric. You can't buy sulfuric. You can't buy anything interesting, it's all prohibited. Thank you! Keep up the good work.
Niclas thanks man! No matter the laws, we will always adapt and overcome to do interesting science at home
conc. sulphuric is videly available, quite pure for drain cleaning..at least in CZ and it is not prohibited by EU regulations, nitrates of all sorts are available as well as all perchlorates except K and Na, diluted peroxide is still available
Well, not in EU then, but it's prohibited in Sweden. Enjoy your freedom to buy chemicals while it lasts. My bet is that it won't be long before you have the same, stricter regulations as we have in Sweden. Diluted H2O2 is available here, and I can get KNO3. But no Ammonium nitrate or perchlorates.
Niclas as far as I see it, EU regulations are much more liberal than Australian regulations and even US in some cases (iodine, red phosphorus are readily available in the EU but not in US). We can even buy stuff like methylamine HCl here or other amines. A relatively near by paint shop even sells 30% H2O2. EU regulations are quite restrictive about chemicals in OTC products (no DCM in paint stripper and low ethylene glycol content in antifreeze for example), but if you order from chemical suppliers online (totally legal, with forms and ID) you can get quite a lot of stuff. Most things are pretty affordable as well.

Bisulfate : eventually comes from sulfur : you made it harder
Am I the only one fascinated by the axe head used as a stand weight?
It's mesmerizing to me.
neighbors look over at your front yard "that kid is so brazen he is cooking meth again in his front yard"
I read in some century old tome that some foaming reactions can be carried out better with a LOT of pure quartz sand mixed in, so that the volume of sand is greater than the other reactants. I have you ever tried this to see if it really works, or if it is like some form of prehistoric chemistry lab trolling?
Daniel Matthews maybeee... Although not sure it would help in this case, given its a thick molten salt mass, but perhaps it's worth trying because it's definitely the worst part of this reaction
Sodium bisulfate monohydrate apparently has a much lower melting point so if you have the anhydrous stuff it might not hurt to try adding an equimolar amount of water to the sodium bisulfate next time.
Here in the states they sell NaHSO4 as the monohydrate
Then you wont get anhydrous acid coming over... but the lower temp would make it run a lot nicer I think, until maybe all the water boiled off? Not sure exactly how that would play out, maybe something to test, cool thinking
The desperate attempt to keep the nitrous oxides from escaping! :D I've never seen any method that did work perfectly, because the monoxide always gets through and is oxidized afterwards... I've used teflon grease back then which did work fine.
bugger on the suckback. would have been nice to see how much you made from that. good footage there too.
Yeah it's usually a very important part of the video to show the final product... But yeah it really pissed me off haha. i get roughly 15ml out of it at this scale.
So I tried this recipe and it didn't take me to the subreddit? What am I doing wrong?
THIS IS JUST AS AMAZING AS THE NURDRAGE SODIUM METAL METHOD!!! THANK YOU!!!!
holy crap $60 for 1l of sulphuric acid ! Man i'm a lot more thankful now I can get 2 gallons for $38 here in the U.S.A .
Ethanol will usually substitute for methanol. In the US the brand Everclear is 95% Ethyl alcohol. Note that "denatured" Ethyl alcohol is usually 10% methanol to make it toxic. (Same ratio as Pear wine or Apple cider.) [Alcohol dehydrogenase (which makesvthe methanol toxic) has a 7000:1 preference for Ethyl alcohol.] Shellac thinner. Also used for fondue or food warmer fuel.
You must love that axe head, I've seen it in quite a few of your videos. Anyway, I really like your channel, keep up the good work
I don't know about Australia, but where I live we have SUPER strict rules with chemicals. KNO3, nitric acid, conc. sulphuric, aluminium powder, it's all illegal.
But you can still buy battery acid, which is ~50% sulphuric and should be easy to concentrate. And at about 10 usd per liter. Just a tip if Australia is as restrictive as here.
Sulfuric acid is almost a waste product it's so common. At least here in the USA, it's a side product of fuel production, and used to go for $5-7 gallon for a medium concentration like you might use for removing stumps or clearing drains.
I used sodium bisulfate to make nitric acid about 45 years ago when I was a kid. No chance of getting H2SO4 then. But I could go to the drugstore and get saltpeter over the counter. I had no recipe to follow but was successful in making HNO3. Turned my fingers bright yellow. Lucky the nitrogen oxides didn’t kill me.
The yellow skin colour really is quite sickly isn't it. I've been hit by droplets a few times, it's never been a big enough amount of acid to actually hurt or even feel it, but it does make those yellow stains. The worst is when it hits your fingernails, because it stains them and it takes so long for your nails to grow enough to move the stains off the edge, your skin replaces itself so quickly
The bigger question is how do you buy potassium nitrate in Australia without being added to some kind of watch list?
Hahahah you fcking serious? ,
It is boring times we live in, difficult for hobbyists.
Point being Kno3 is everywhere. I get into model rockets and buy by the kilo for under $20 👍
And fck the watch lists! For god sake they know EVERYTHING we do! We're not doing anything illegal so fck em 😅😅😅
In the U.S. you can get sulfuric 1.5 liter or so size for $13 USD at Walmart. It was the Lightning brand and claimed 100%.
Teflon tape works as a joint seal
Thank God for Duda Diesel. 'murica
Lol, you and me both. It's what, 8 bucks for a liter here?
For small amounts it is still far cheaper and easier to generate HNO3 on location, after shipping charges one bottle from duda is half the cost of a basic distillation kit. I'm stuck in a spot where I just need a few grams of silver nitrate but every where I look I end up with a minimum of $60 invested (cost of 25g AgNO3 of uncertain quality on amazon, double that for a supplier of known quality like sigma.) when the raw materials for 25g would cost me $15 if I had a distillation setup, but buying the complete apparatus is over $100 even with the questionable cheap stuff from china. (only $15 because I already use sulfuric acid and KNO3 around the farm so there is no waste, all I need then is fine silver at $20 per troy ounce, $0.67per gram or $11 for 25g of AgNO3, though I really only need a couple grams. The lowest cost smallest amount of ready made HNO3 is however over $80 after shipping.)
Regarding sulfuric acid, if you can still have KHSO3 you can pyrolise it to SO3 (sulfuric acid anhydride) very easy to isolte pur by distilliation; it working but you need a Bunsen burner or similar +you can access oleum (careful dilution is very exothermique) or sulfuric acid whatever grade you want. - it s sulfur trioxide it oxidize everything
I m Phd in chemistry and canot acces is saddly but really need it; a tip to have SO3 pure is an old procedure; heating a past of H2SO4 with phosphorus pentoxide around 170°C and collectinf SO3 byt distillation (and redistillation for high grade, storage as oleum is better)
I was thinking about this again. To keep from distilling at the melting point of bisfulate, why not add water and distill to an azeotrope of nitric acid and water at normal temperatures? If you want it more concentrated, you could always distill from sulfuric acid, add pyrosulfate, or another drying agent.
Pretty sure you would just distill water and not have any product because we are starting with a weak acid and a strong acid salt. For example you can distill HI from KI and H3PO4 which would absolutely not happen in an aq solution
I've noticed that the Aussie and Canadian chemists have posted demos of preparing basic lab reagents, esp. mineral acids & organic solvents. While the videos are very cool, I've always wondered why. Here in the States I produce nitric acid by giving the clerk at my local lab supply store some money, stuffing it into a backpack and taking it home on the bus. Is it difficult to obtain these substances in other countries? Please explain ... and do keep making videos.
Lab supply stores in most countries sell reagents only to registered labs. So if you don't have the paper you must acquire it from online suppliers which 1) tend to ask the same questions as the normal lab supply stores (not everyone of them, I managed to buy my nitric acid online) and 2) they can often get the police knocking at your door if you buy too much.
In addition lab suppliers only sell azeotropic nitric acid, but for a lot of applications (ahem, explosives) you need RFNA which is obtainable only by the reaction between H2SO4 and KNO3.
Using sodium sulfate monohydrate works much better with greater yeld. It´s melting point is like 140 i think, so much less HNO3 gets destroyed by the heat. NurdRage explained it very well in one of his videos..
In the US I can get technical grade sulfuric acid at about 97% for approximately $8 per quart
A thin iron wire around the Teflon tube at the union, and twist it tight like a mini hose clamp. It is however a consumable part. I have a hand made unit that is sealed in this manor.
Buy your sulfuric acid from battery stores, or vehicle stores. I buy my sulfuric acid by the 5L bottle from Covs. Costs like $15 for the bottle. 37.5%
Gordon Freeman
here in Mexico you can get 99% sulfuric acid at only $ 6 per liter. Ironically it is more expensive to buy drain cleaner than concentrated sulfuric acid
Knock knock. Who's there? Sodium bisulfite.
Knock knock. Who's there? Still Sodium bisulfite.
Knock knock... KNOCK KNOCK!
-.-
what heating mantal is that and where did you get it
Very interesting video. Good to see all these preps on RUclips. Back in the 'old days' (mid 1960s) when I started as a teenager, (no RUclips of course, just had to trawl through the texts) sodium bisulphate was the only easily obtainable alternative to sulphuric acid, and it was even in kids' chemistry sets (bet it isn't now). Most of your NO2 overflow would make mostly just nitrous acid with the water, which would decompose again. Better might be to dissolve it into H2O2, which would help oxidize it up into HNO3, and without any contamination. I used to make some small HNO3 preps just by heating lead nitrate and absorbing the NO2 into H2O2 (with a big enough funnel, of course!).
Wow its so expensive in some parts of the world. Here in Turkey the price is 1.5$/kg of 98% sulfuric acid.
The system had too much space inside and that makes the sun/clouds variations to severely alter the temperature and therefore the presure inside the system, therefore causing sucktion. ..i guess.
Maybe use an _actual_ suck back trap? (flask with two tubes)
Here in the States, sulfuric acid drain cleaner (normally 93-94%) is under $20 a liter, and less in bulk. I got 4 pounds of NaNO3 fertilizer for $8, not too long ago, and KNO3 stump remover is maybe $6 a pound.
So at higher temperature nitric acid distills off without much decomposes into NO2 but at lower temperature it decomposes and not distills .... that doesn't make sense... ??
Fascinating video! Loved it. Loved the bisulfate idea! Back-in-the-day I did all HNO3 distillations at reduced pressure using an aspirator pump and vacuum adapter. That held the ground glass joints tight. But it required a very cold condenser. So I ran superchilled windshield wiper fluid through it. (The wiper fluid sold around here is good for -30C, and was chilled by circulating it through a bucket of CaCl2 brine permanently stored in our coldest chest freezer.) As a plus, the resulting distillate was water white. Even the 100% conc. acid was white. It was delightful. I miss those days.
I know it’s an older video but I have to deal with the same tubing issues, If you get a chance zip tie a metal clothes hanger down the tube and it makes it bendable at least enough to shape it where it won’t knock things over.
$60 per liter?? my local hardware store sells 96% straight sulfuric acid (very few impurities and no dyes/inhibitors) for about $24 per gallon!
Ya but the problem is it isn't sold in a good unit of measurement so it's practically worthless
(i'm salty because i'm jealous)
Personally I hate imperial measurements, but it's what they're selling so it's what I'm buying :P oddly enough though, nitrates are becoming rather difficult to find for me, even online. Fireworkscookbook.com is one of the few places I can still get KNO3 for a reasonable price
Where are you from that you can get sulfuric acid $24/gallon? I can only get it at $25/2.5 liters
What country? I am packing my bags already :)
There's a company that mix drain cleaner in the state that I live in that makes it so clean and upwards of 95% pure sulfuric acid it's cleaner than most technical grade acids that I have seen. I mean if I don't need 98% I feel perfectly fine using it straight out of the bottle it is crystal clear. There are no Inhibitors whatsoever in it I'm trying to think of the name of it while I type and I just can't think of what it's called but I mean it's cheap to it's like $8 for a quart I typically distill the stuff and stored at 98% so easy and so clean
So nitrate salts + sulfuric acid won't create nitric acid unless it's distilled?
it does lmao but distillation is to separate it idiot.
Ah mate, I’ve been lucky with my chemical collection. 5l sulphuric and 5l nitric acid are $40 for me. Sulphuric is 98% and nitric is 68%. It’s a shame how stupidly annoying it is to get chemicals these days
Why is it called bisulphate? I only see One sulpher and not two.
Try FEP Tubing or PTFE Lined Tubing. It's still stiff but might be easier to work with.
From my experince, as I remember this method instead of H2SO4 + KNO3 is much less efficient and there is high risk of cracking the glaswere becouse of high temperatures. Like most of KNO3 decompose or I think it just can't escepe the bottom flask. I don't know how exactly looks like the prices in your country, I remember I ones seen something like 30$ per 0,5l on united nuclear lol :D for no reason, in my country H2SO4 is 1l for 4,5 US $ since it's very cheap in massive production maybe even 1,13$ per liter. However maybe if H3PO4 would be cheaper in your country you can use it also to make HNO3- I tried it one time and it worked.
I have never seen nitrogen dioxide turn green unless there was copper in the system that is so bizarre. I have made so much nitrous oxide in my life that I can't even imagine a container large enough to hold it all I have never seen it turn green under any circumstance
wow I had no idea chemicals could be this expensive. here in poland you can get 98% sulphuric acid for 7 eur/L and KNO3 for 5 eur/kg
Are you using rubber gloves while working with nitric acid?
U know these can catch fire on contact with nitric acid?
and about using muriatic acid?
I always wondered something. Supposedly i heard that if you cool NO2 to a certain point, it will form a blue liquid NO3. I have to wonder if you could drip weak or moderately weak H2O2 into that mixture to get a really good recovery and conversion to more acid?
Hi, do you have any way of extracting nitrates out of fertilsers or ammonia or anything ? I live in Aussie also and its a pain in the arse. And i dont want to piss on manure for 10 months to make pottasium nitrate.
I mean building a spark gap high voltage thing that creates nitric acid from nitrogen in the air is a great solution. I have enough nitrates that I probably won't do that here though, and I'm notoriously bad at electronics projects
@@ExtractionsAndIre yeah i saw Codys lab spark thing. I was trying to avoid high voltage. Unless a bunch of spark plugs work ? 🤔
No idea. High voltage is pretty dang frightening
Yeah... I was once trying to make KMnO4 out of "rubbish" as a sort of modern-day "alchemy" project but the piss/manure combination for KNO3 put me off too.
Ive been feeling like my lab is way too messy lately. Im glad I saw this episode because holy shit I'm fucking lucky.
KNO3 still available on Amazon where I am
Really? I get all my ammonium nitrate from cold packs. Just bought some the other day at the grocery store. H2SO4 and KNO3, however, I have to order online from a biodiesel company. I guess things are handled differently depending on the country you live in. The H2SO4 goes for $12 USD per liter.
I might wanna add that putting H2O2 into the scrubbin water will increase HNO3 yield.
Uliemm151 oh yes I forgot to mention! I do do that sometimes, it does help yes. Good thinking
Couldn’t you use Teflon tape instead of grease?
Wonder if you could run a dry trap.... is nitrogen dioxide reactive enough to support substitution in a dry powder? Tube into the bottom of a canister of 'fluffy' powder, or powder mixed with cotton waste (and I'm thinking now I'm just asking for a fireball...)
Stuff like this leads me to think you need to make a large water trap to plug these things into, just a jar with two tubes in the top, gas in and gas out, then just lead the outlet into a water jar. It'll pull vacuum as it cools but all it will ever accomplish is sucking the water into the trap, which is large enough to fully contain the water in that trap. It literally cannot physically suck so bad it gets water... though it could get air, once the water trap is empty.
How many times does he have to tap the buckets 3:07

in us u can get 93% sulfuric acid drain cleaner for really cheap, then you just distill and dry it for pure sulfuric
Hey I'm about four years late on this video, but I've seen you use teflon tape a couple of times and I was wondering if the type of heat shrink you'd use on electronics would serve well at a high (but not VERY high) heat to hold on teflon tubing. As a youtube commenter, I have followed standard procedure and not googled or researched this.
I realize, on slightly more thought, that if the connection wasn't perfect on the teflon tubing and any acid escaped you'd end up with what I can chemically describe as a rubberized hellmass,, massively limiting the chance this is useful as an idea.
why is suphuric acid this expensive where u live? I can buy 1L pharmaceutical grade for 14€.
Silica dioxide works well to stop bumping
But I know that sodium bisulfate mono hydrate melts at 58 degrees centigrade. Wouldn't it be easier if you first recrystallized pool pH down (which is usually anhydrous) so that you get the monohydrate and you don't have to heat so much?
Don't take everything you read off of wikipedia at face value, sometimes important info is left out dude. It's misinformation to call it "melting" when really the salt just dissolves in it's own water. If you look online the dehydration temperature is listed at 58°C for sodium bisulfate monohydrate. Essentially it just farts off water above that point. In another way, if it did work that would introduce water into the system and it wouldn't be fuming nitric acid anymore. Hope that helps
Spooky Wizard
Actually, the monohydrate would be preferable for most of us, since most of us want to make 68% HNO3.
On the other hand, if your procedure actually requires fuming HNO3, you would definitely want to use anhydrous sodium bisulfite.
I’m just saying this because most of us want to make 68%.

If Lab grade H2SO4 is not readily available, is it practical to buy battery acid from an auto shop and purify it at home?
I mean, sort of. It is definitely achievable. You can get reasonably concentrated acid by just heating it in open air, but to get it all the way it can go, you really need to distil it. I have a video on that, and I guess it's practical if you have the gear, but even then it's super dangerous and not pleasant or fast to do. If you don't have good glassware, don't even dream of distilling it. Depending on the circumstance, you're often better buying 'dirty' concentrated drain cleaner sulfuric acid which is already concentrated, using it directly or cleaning it up first.
Battery acid isn't always pure anyway, I got my first bit of sufuric as 30% battery acid and I concentrated it, which resulted in fairly concentrated acid and something that crystallise out the bottom, possibly sodium sulfate. So I mean nothing is lab grade unless you make it so really. Stay safe!
Myst was killed by the dangerous experiment called becoming a dad. Much rip. May he forever be tormented by his little rascals in his new journey.
In the U.S. I can buy potassium nitrate for $12.99/lb and sulfuric acid at $9.99 per litre at the same store 5 min from my house
So this way gives RFNA while the sulfuric acid method gives WFNA?
Not exactly, the sulfuric acid will also give RFNA as you make some nitrogen dioxide as a by product there too. You really only get WFNA if you distil under vacuum to avoid decomposing it with heat, or you chemically clean it up with like urea
Great overview and a well scripted video and yeah I've seen the other video too but what really perplexes me is what REALLY is the concentration of the nitric acid distilled over?I know the traditional method has higher concentration of 99% due primarily to sulfuric acid holding back the water and lower temperature of 130C favoring a higher yield of nitric acid but did you try to determine concentration of your distillate and reaction with copper?
I mean ideally it should be 99% too, just because there's no water in the reaction flask to distil over with the nitric. I've never done a titration actually, but i've used this as RFNA for the last few years without it acting like it wasn't RFNA. It doesn't quite set nitrile gloves on fire, but it definitely smoulders them, a sign that it is very concentrated but perhaps could do with another distillation over sulfuric acid to really achieve that 100% nitric acid target
Thanks for that I was planning to buy sodium bisulfate in the near future weighing on a maybe but your corroboration made me dig my heels in further and now I'll take a rain check on it though my query was I currently own drain opener acid can that be used to acquire fuming nitric acid?
60 bucks a litre thats nuts i just bought a litre of sulfuric acid drain opener for 5.99 usd
Is it possible to convert nitrite to nitrate? Curing salt for meat can be had for a decent price that's sodium nitrite. I'm just brainstorming ideas for solving the nitrate availability issue in some places. On the other side of the pond in the US those cheeky b*stards can buy pure ammonium nitrate prills in bulk 🤯
In my countrie, sulfuric acid drain cleaner cost 6 bucks for a liter or a liter and a half.
35% sulfuric acid can be obtained from old car batteries. Nitrate salts can be obtained from urine Hey or straw and hardwood ashes
Dear sir this formula of acid and your condenser of stove name Thanks
Faris Faris thanks, you too
Is it yellow? Yes? Put it in the rubbish bin.
A lot of channels are going to Full30
Nice vid mate
9:36 If it did attack the grease then it sure as hell was not the real grease PTFE in a PFPE oil, that is the only thing that should be used for this, since nitric acid does NOT attack and breakdown PTFE or similar compounds, period.
But you have to get the real stuff and its not certain even schools have it since its very expensive.
I have a small 100 ml tube of the right stuff and that cost $140 but then you get the best of the best that would hold for anything.
Agreed. It was high-vacuum oil, but it wasn't the super expensive completely-fluoridated stuff. You're right that the school don't have the PFTE one, I used the grease that we used all through the labs in university, and its good for most things except real extreme conditions like conc nitric. I've been thinking of buying some of the good shit for a while, but it is hard to justify the large upfront cost for it. Maybe when I get a real job haha
You pretty much just used it once on the sealing surfaces and it will then be there for a long time. Since it does not react to anything you dont need to take it of and put new on all the time and thus a small tube will last a long time.
Sure, it will last a really long time, still doesn't mean I can afford it :P Assuming it isn't sold in 10ml tubes. That would be more practical for me
I of course didnt meant in that way, just that its dam good since it can stay on for a long time even when doing other chemical things which is really neat.
Nice
You should be called “The raggedy man chemist” From Mad Max 2 beyond thunder dome.
Because of how you always Jerry rig everything together to make it work. Then you’ll need a dog and a shotgun. And a really cool car with a supercharger sticking out the hood. 😊😊😊 that would be really cool.
In canada, 1L of sulfuric acid is like 11$ lol
