Why don't you make nitric acid distilling a mixture of NaHSO4 and KNO3 (not in solution) ? I think you can get really concentrated HNO3, since there should be almost no water distilled off. I am not 100% sure though.
could one use HCl instead of the last expirement, and isn't obtaining NO3 salts from gunpower is far more easier than from furtilizers? (just bust open old fire works add water and filtrate the solution)
Wubbly Bubbly Using non-pure salts such as fertilizer may produce an impure product. The higher purity salts, the better. As far as the copper goes, it doesn't need to be 100% pure; it just needs to be copper and not aluminium, magnesium, zinc, etc.

I know in the US products require a materials safety data sheet (MSDS). Those tell you what's in the product. You can general find those on the manufacturers website. I usually just Google " X MSDS, where X is the name of the product. See if such a thing exists in Australia, that should tell what they might be denaturing the hydrogen peroxide with.
quick question when testing this third method of making Nitric acid as soon as i add the sulfuric acid to the nitrate salt (in my case KNO3 ) large amounts of nitrogen dioxide is released immediately. how have you made your acid clear ( as mine is a yellowish color ) and also so that it doesn't immediately react with the nitrate salt. please respond with help. subtotalkiller
Maybe English is wrong because I am Japanese student... The reaction of this video is possible in Sodium nitrate,Potassium nitrate and so on. But, is it possible in Ammonium nitrate? I think that the complex is produced in the reaction. So,I think that Nitrogen dioxide and Ammonia gas occurs in the reaction. After all, Ammonium nitrate is produced.
I tried the first method because I don't have all the lab equipment but I could not get a reaction....the potassium nitrate I used was purified from stump remover (spectracide) and I purified twice for a higher nitrate concentration using the recrystallization method. I used muratic acid (31.45%) and a lot of wire I stripped at exactly 40 grams. Am I not getting a reaction because of the lack of concentrated HCl? If so can you suggest a method for concentration I can do without going out and buying $200 worth of lab equipment?
When I made this years ago, using the exact same methods here, I had to be sure that the copper I had was not coated in any plastic covering. What I did was use around 10-2 gauge wire that was used for carrying very high current. Change up you wires and give that a try. P.s. the KNO3 and HCl seem to be fine, and if I recall I used the exact same concentration of HCl, and the same stump remover for all my KNO3 needs.
You need to set them aside (muriatic nitrates salt mixture) for 15 minutes to fully convert HCl to HNO3, then heat them by put the mixture (in glass beaker) in hot boiling water for 3-5 minutes, i hope its works (lol non english speaker)
Another cause is the copper, make sure your copper is plastic free, then etch copper oxide layer in muriatic acid until its shiny new copper, use copper wire to increase the surface.
I wanted to show a wider range of approaches. If i didn't use water some viewers may get the impression water can't be used. Then i'd get questions like "couldn't you use water instead of hydrogen peroxide?" by showing both we see more perspectives and get a better handle on the underlying chemistry and how it can work in different ways.
Great video! Thanks for making this! When using sulfuric acid, can you use battery acid from an auto shop, or is that too dilute? Do you need to boil it down to a higher concentration?
Instead of actually understanding the origin of the rule or why it applies you rely on unscientific catch phrases and insults? Your so called "basic rule" only applies to certain limited set of circumstances. Primarily it applies to adding water to concentrated sulfuric acid. But if you don't believe me try this: Grab some vinegar in your kitchen (an acid) and add water to it. NOTHING will happen other than getting some diluted vinegar. Try to be smarter and less insulting will you?
I learned in High School chemistry 40 years ago to "Add acid to watah, just like you oughta." I haven't run into any circumstances where that caused problems, even with vinegar, so it seems like a useful guideline.
@@brandonknight7240 im glad i wasnt the only one who heard this, but to dissolve copper means that the acid and coppers by product is water soluble. So hydrochloric acid can destroy copper its byproduct isnt water soluble. I believe is the answer
4:05 I wanted to just point out that you can distill fuming (above concentrated) nitric acid, you just need to use concentrated nitric acid and concentrated sulfuric acid and distill. The sulfuric acid likes water much more and will keep it in the flask while the almost pure nitric acid distills over. Great video!
70% nitric acid is an azeotropic mixture, you won't get better percentage by distilling it alone. You'll need a dehydrating agent like sulfuric acid. But unless there is a specific need, i don't reccomend doing it since 70% nitric acid is perfectly good for the vast majority of reactions.
"How to make nitric acid? Just mix hydrochloric acid with...." "How to make hydrochloric acid? Oh, just mix sulfuric acid with...." "How to make sulfuric acid? Easy, just mix nitric acid with...." GAAAH! This is starting to resemble those irreducible complexity paradoxes from theory of evolution! ;[ How does one BOOTSTRAP this process to begin with when there's no acids around yet, just bare nature?
iron (ii) sulfate occurs pretty commonly in nature as a mineral and decomposes at 650 degrees c if you wanted a practical way to make a strong acid without access to any of them today nurdrage has a video where he makes HCl from sodium bisulfate (very easy to get as a ph lowering chemical in pools) and table salt.
Thank you for the great information. I used to love my Chemistry classes in college and Nitric acid was used in many experiments but getting a supply has never been easy. I saved all my old lab workbooks and notes and would love to set up a lab and do these experiments again.
"Here I will show you three different methods with three different nitrate bases you will not be able to buy, find, or make. But you will still waste 7 minutes watching this."
Plenty of things on youtube that are described but not accessible to most people. Like how to make nuclear weapons, jet aircraft, rocket ships and cars.
Used to have a pint sized bottle of Nitric Acid for testing for gold, wound up giving most of it back to lab store just got a little paranoid some how the bottle would wind up getting broke since I didn't really have a good place to put it and I would wind up with major contamination mess on my hands.
"Copper is costly"? 32 grams is about 25 cents worth. But it's actully free. Just go out on garbage night and salvage some. I get at least 5 to 10 pounds of it every time I go out looking for it.
first one is not working, the copper is not reacting and no gas is being produced EDIT: Actually It worked awesome! Turns out it needs to be a certain temperature. I guess the winter air outside was too cold!
I don't believe it's comparable to the Leidenfrost-Effect. My guess is that the Copper forms Copper Nitrate in the Nitric Acid: Cu + 4H+ + 4NO3- -> Cu(NO3)2 + 2NO2 + 2 H2O But even though Copper Nitrate is highly solluble, it won't dissolve in fuming Nitric Acid, due to the high Nitrate-Concentration shifting the Chemical Equilibrium to the left side: Cu(NO3)2 Cu2+ + 2NO3-
Well since this comment was a long time ago, I'm going to try and summarize my current thoughts. I think I was trying to say similar to the Leidenfrost-effect in the following way. If you were trying to melt Ice quickly, you would logically think Ice would melt quicker at higher temperature, but it's a little counter-intuitive to think that ice melts slower in boiling water. Likewise, If you were trying to react copper with Nitric acid, you would think higher purity acid would react with copper quicker, but It's also, counter-intuitive to think that a higher concentration slows the actual reaction. Bare in mind, this was 3 years ago, and I think I'm summarizing my thoughts accurately. :)
I agree with you that the intuition behind it is very similar to the Leidenfrost effect, everyone in the comments thread is thinking way too analytically. In the Leidenfrost effect, the desired action is inhibited by a gas layer formed by the action itself. In passivation, the desired action is inhibited by a protective layer formed by the action itself. They are really similar, I think people want to just show off their intelligence and only know how to via disagreement.
I'm a Nitric acid panel operator in a fertilizer plant. I am using my girls channel at the moment. I retire in 12 years. Sounds like you are ready to step up and take my place..Cheers!
Will the 2nd and 3rd method work on silver? And instead of using 30% hydrogen peroxide can I use 3%( standard hydrogen peroxide bought at store) and still get better results then using only H20?
nitric acid .. and nitrile gloves? .. latex gloves? wont nitric acid cause those the burst into flames? wouldn't you be better off wearing none? and just have a bucket with sodium bicaranate and water handy?
Thebarnardfactor hey can you possible help me, if so let me tell you what happened so I tried the gas generator method and let no2 run through tubing and bubble into 50 ml of water, and I let it run for a good 15-20 minutes and I tested it by dropping copper into it and all I it did was bubble and bubble a lot but absolutely no color blue color change was observed nor was there any brown nitrogen dioxide gas produced, I've repeated this experiment multiple times now and I still get the same resultes, please help if you can:)
Yeah, same here, no brown Gas appeared. But I did do a ph test after and it was acidic. It barely reacted with the copper at all. I used the first method though. Note, don't go anywhere near the dead reacted mixture when you put in the aluminum. I was outside, and i still breathed in a ton of fumes.
Maybe it's at a really weak concentration like nurdrage said in his video thanks for replying, I've also had the suspicion it might be nitrous acid and a plane to run air with a bubbler in to the solution with the no2 gasses bubbling through it to oxidize the hno2 (nitrous acid) to hno3 (nitric acid) since there is a mixture of both when bubbling no2 through water
Typically used in organic synthesis as stated above, nitrate salts are found in fertilisers which allow growth much faster than what occurs naturally. The nitronium electrophile is used in making many medicines too, often for low heart rate disorders :)
***** you definitely look like an idiot because it is known for everyone that the concentration of toluene in things like paint thinners is too low to make anything. Tnt is not made anymore, by amateurs at least
Your videos are very instructional. Im a small precious metal refiner and the cost of nitric acid is very expensive. Im almost prepared for processing 6,000 grams of silver and another 350 grams of some karat scrap gold. Im considering buying a simple distillation aperatious and wondered if maybe you could counsel me. I need to produce about 1.25
Your description in the video says concentrated hydrochloric acid. When I have shopped for this, I have seen the word "concentrated" on acids from 37% all the way down to the 31.45% that you can buy at walmart. Are any of these okay to use, or do you need a specific concentration?
Dwight Gordon. I have the same question. I just recently acquired amonium nitrate, the only Hydrocloric acid I can access easily is 31% (muriatic acid) Have you found out if this is sufficient?
I'm still in the research stages, haven't acquired any as yet. If we haven't gotten any response by the time I am ready to try it out, I'll let you know what I find.
Dwight Gordon. I'm about to test 31.5% HCI myself. I found some old cold packs that contain amonium nitrate so I'm finially able to produce some nitric acid to process a bunch of high quality gold connector pins I have. I'll post my results as well
Here after watching a bit of a news report today (5th August 2020) about a chemical explosion in Beirut. Word has it that an ammonium nitrate storage silo exploded in the neighborhood. 70 dead, and 3,000 or so injured so far. It's an extreme thing, but I think it emphasizes the need to keep chemical silos as far away from residential areas as possible. So much destruction, and there's that large red cloud of nitric acid gas...☹️ This may be updated as more info becomes available.
In this video I show why you should not wear gloves when handling nitric acid (unless they are specifically rated for it): ruclips.net/video/3cKZQOetBiM/видео.html
The distilled from the grocery store near me contains ozone will that be a problem or do I need to air it out so to speak before using it ? Distilling my own has proven to not only be a pain but quite time consuming
shiuldn't you be careful witha few types of gloves? these gloves are fine, but some gloves ignite on contact... oh and. where do you find a condencer like that? I cannot find it
You said only nitric acid can destroy copper. Ferric chloride is used to dissolve copper traces when making pc boards The first one I tryed used a aluminum tray and it burned right through the bottom
Hi. Just wanted to ask, on the 2nd method is the toxic gas stays on the vacuum flask? does it (toxic fumes) not goes out along with the nitrogen dioxide to the graduated cylinder?
Can someone please explain to me why you cannot simply react HCL + NaNO3 --> NaCl + HNO3 ?!?? just set this up as distillation like nurdrage method #3, but replace sulfuric acid with HCL.. You can re-distill to azeotropic, but it seems way better than do deal with dissolving copper and bubbling through H202
"Pure" Sulphuric Acid will also not attack Copper very quickly without having water present. I didn't know Nitric Acid acted this way. (I worked in a precious metal recycling lab...with George Gajda - look him up). He taught me some interesting chemistry.... Disclaimer: I'm not a chemist.
Why do you say only nitric acid can disolve copper? I etch the copper off circuit boards with just hydrochloric acid and hydrogen peroxide. I end up with copper in solution. Copperchloride.
Is it just me, or does it appear that the 1st batch of Acid is stronger than his 2nd? Seems like the coper is being eaten away much fast in the 1st test... IMHO.. Thanks for the videos!!! :)
I’m trying to view your video with the nitrate test link in the description. However, it says it’s private. I’m not sure if that is intentional, if so could you recommend another video for me please?

@@ductoannguyen7595 yeah thats what happened ! Solubility of NO2 was drastically lowered
Does using other salts than you used produce not as pure acids, or does it not matter? And does using pure copper make a less contaminated acid?
Wubbly Bubbly Using non-pure salts such as fertilizer may produce an impure product. The higher purity salts, the better. As far as the copper goes, it doesn't need to be 100% pure; it just needs to be copper and not aluminium, magnesium, zinc, etc.

Any acid should work, but it'll bring over water when you distill it. Using concentrated acid is necessary to create fuming nitric acid.

They are really similar, I think people want to just show off their intelligence and only know how to via disagreement.
I'm a Nitric acid panel operator in a fertilizer plant. I am using my girls channel at the moment. I retire in 12 years. Sounds like you are ready to step up and take my place..Cheers!
canary skin?
How concentrated does the sulfuric acid have to be? Is battery acid enough? (Battery acid is around 36-38 percent)
You need 93 or 98% acid
Battery acid might not be enough but you can boil it for concentrating it
Will the 2nd and 3rd method work on silver? And instead of using 30% hydrogen peroxide can I use 3%( standard hydrogen peroxide bought at store) and still get better results then using only H20?
They should work.
Dilute hydrogen peroxide would still work,maybe very low yield but still be better than water
nitric acid .. and nitrile gloves? .. latex gloves? wont nitric acid cause those the burst into flames? wouldn't you be better off wearing none? and just have a bucket with sodium bicaranate and water handy?
+Wade Hutchinson that's vinyl gloves, not sure what the fuming nitric acid will do to it though.
No matter how i do this, it won't work.
Im using ammonium nitrate, and a strong cleaning chemical that contains hcl.
What you need is a concentrated sample of HCl so the cleaning solution won't work as well
Would 32% muriatic acid work?
Thebarnardfactor hey can you possible help me, if so let me tell you what happened so I tried the gas generator method and let no2 run through tubing and bubble into 50 ml of water, and I let it run for a good 15-20 minutes and I tested it by dropping copper into it and all I it did was bubble and bubble a lot but absolutely no color blue color change was observed nor was there any brown nitrogen dioxide gas produced, I've repeated this experiment multiple times now and I still get the same resultes, please help if you can:)
Yeah, same here, no brown Gas appeared. But I did do a ph test after and it was acidic. It barely reacted with the copper at all.
I used the first method though.
Note, don't go anywhere near the dead reacted mixture when you put in the aluminum.
I was outside, and i still breathed in a ton of fumes.
Maybe it's at a really weak concentration like nurdrage said in his video thanks for replying, I've also had the suspicion it might be nitrous acid and a plane to run air with a bubbler in to the solution with the no2 gasses bubbling through it to oxidize the hno2 (nitrous acid) to hno3 (nitric acid) since there is a mixture of both when bubbling no2 through water
nice but what is it useful for
to burn ex's face
HalfLife2Beta loooads of stuff, can be used to make nitrate salts, to add nitro or nitrate groups to compounds, has many aplicatons
making nitrate salts, making nitrocellulose
Typically used in organic synthesis as stated above, nitrate salts are found in fertilisers which allow growth much faster than what occurs naturally. The nitronium electrophile is used in making many medicines too, often for low heart rate disorders :)
*****
you definitely look like an idiot because it is known for everyone that the concentration of toluene in things like paint thinners is too low to make anything. Tnt is not made anymore, by amateurs at least
A@1:30 : I thought Nitrogen Dioxide dissolved in water to make Nitrous Acid. Not Nitric Acid. Am I wrong?
Your videos are very instructional. Im a small precious metal refiner and the cost of nitric acid is very expensive. Im almost prepared for processing 6,000 grams of silver and another 350 grams of some karat scrap gold.
Im considering buying a simple distillation aperatious and wondered if maybe you could counsel me. I need to produce about 1.25
Your description in the video says concentrated hydrochloric acid. When I have shopped for this, I have seen the word "concentrated" on acids from 37% all the way down to the 31.45% that you can buy at walmart. Are any of these okay to use, or do you need a specific concentration?
Dwight Gordon. I have the same question. I just recently acquired amonium nitrate, the only Hydrocloric acid I can access easily is 31% (muriatic acid) Have you found out if this is sufficient?
I'm still in the research stages, haven't acquired any as yet. If we haven't gotten any response by the time I am ready to try it out, I'll let you know what I find.
What I do know from watching other vids is that the words "hydrochloric" and "muriatic" are used interchangeably for the same acids.
Dwight Gordon. I'm about to test 31.5% HCI myself. I found some old cold packs that contain amonium nitrate so I'm finially able to produce some nitric acid to process a bunch of high quality gold connector pins I have. I'll post my results as well
Description says you can use different concentrations, but adjust the amount of water so the acid:water ratio remains the same as in the video
How much concentration does the hydrocholoric acid method produce in the nitric acid?
If you read the the title you'd find this is not a video on how to make bombs, but how to make nitric acid.
I shower with concentrated nitric acid thrice a day (warm and bubbly), so don't bother about the warning.
Hey Mr.NurdRage!Can I use 17% HCl or sth like 23%?This is the only concentration sold in the shops in my area!Will it react with NaNO3 to make HNO3?
Granulated copper wire is good indirect source for gold. #1and #2. copper
And how do I make sodium nitrate?
Ammonium nitrate cold packs+sodium hydroxide drain cleaner
Here after watching a bit of a news report today (5th August 2020) about a chemical explosion in Beirut.
Word has it that an ammonium nitrate storage silo exploded in the neighborhood. 70 dead, and 3,000 or so injured so far.
It's an extreme thing, but I think it emphasizes the need to keep chemical silos as far away from residential areas as possible.
So much destruction, and there's that large red cloud of nitric acid gas...☹️
This may be updated as more info becomes available.
Wonderful👏 now I'll combine my nitric acid with Ammonium bicarbonate 😀
I'm here watching to prove that the platinum is the catalyst to make nitric acid from ammonia. Thanks to Dr. Stone. Season 3 Episode 11.
what about potasem nitrate +sulferic aicd
What is it exactly you mean by nitrate salts? I take it that potassium nitrate won’t work for the last demonstration then?
potassium nitrate will work for sure
Watching this in the event of a mass petrification event that immobilizes the entire human race for 3700 years
In this video I show why you should not wear gloves when handling nitric acid (unless they are specifically rated for it):

Thanks MR. SLAV
The distilled from the grocery store near me contains ozone will that be a problem or do I need to air it out so to speak before using it ?
Distilling my own has proven to not only be a pain but quite time consuming
shiuldn't you be careful witha few types of gloves? these gloves are fine, but some gloves ignite on contact... oh and. where do you find a condencer like that? I cannot find it
will the second method better for gold recovery, as nictric acid is very hard to get.
good video but why, wen you use conc. sulphuric acid and pot. nitrate, you don't respect the molar ratio? there is some pratical motivation?
What are the stats on your concentrated hydrochloric acid? Soooo many variations out there. 32% seems pretty weak and does not work in this process...
You said only nitric acid can destroy copper. Ferric chloride is used to dissolve copper traces when making pc boards The first one I tryed used a aluminum tray and it burned right through the bottom
Hi. Just wanted to ask, on the 2nd method is the toxic gas stays on the vacuum flask? does it (toxic fumes) not goes out along with the nitrogen dioxide to the graduated cylinder?
Can someone please explain to me why you cannot simply react HCL + NaNO3 --> NaCl + HNO3 ?!?? just set this up as distillation like nurdrage method #3, but replace sulfuric acid with HCL.. You can re-distill to azeotropic, but it seems way better than do deal with dissolving copper and bubbling through H202
"Pure" Sulphuric Acid will also not attack Copper very quickly without having water present. I didn't know Nitric Acid acted this way. (I worked in a precious metal recycling lab...with George Gajda - look him up). He taught me some interesting chemistry.... Disclaimer: I'm not a chemist.
Can we use muriatic acid to replace hydrochloric acid ?
Muriatic acid is only 20% pure I think
Thank you
Yes
will pouring iron instead of aluminum work to extract copper from the mixture?
Why do you say only nitric acid can disolve copper? I etch the copper off circuit boards with just hydrochloric acid and hydrogen peroxide. I end up with copper in solution. Copperchloride.
Is it just me, or does it appear that the 1st batch of Acid is stronger than his 2nd? Seems like the coper is being eaten away much fast in the 1st test... IMHO..
Thanks for the videos!!! :)
Thank you for your second method of HNO3 production. I can do this make some acid to finally process various ewastes for gold recovery and refining.
Could you use sulfuric acid from car batteries or would it have impurities that would mess up the chance to get pure nitric acid?
I would say the best option is to simply... buy the nitric acid if you need some 😂
Too bad it's a controlled substance though...
Thanks, this is gonna be really helpful for... A project i'm working on
I’m trying to view your video with the nitrate test link in the description. However, it says it’s private. I’m not sure if that is intentional, if so could you recommend another video for me please?
Could you tell us how to make pure colorless nitric acid?
