Hi, I made pyrophoric iron once by heating rouge (fine Fe2O3) in a stream of hydrogen. It's described in a post on sciencemadness. It was a complete surprise, I didn't expect the iron to ignite. I love your videos, and am so glad you are continuing. You have had a tremendous impact.
I'm visiting family this week so there likely won't be a video. But i'll be back end of next week. I'm currently working out the steps to make Daraprim/Pyrimethamine from domestically available chemicals. I'm not sure if i'll actually make the chemical but it's a long-term project to think about.
I've been fascinated with this video for a while now and I've been working on making this myself. I thought I had done something wrong earlier because I was just left with a brown solution after adding the iron chloride to the oxalic acid even after it had completed cooled. I decided to pour the solution into a new container and the iron oxalate crystals began forming spontaneously and raining to the bottom of the flask. It was awesome to watch and it's still forming crystals after two hours. I can't thank you enough for the inspiration you have provided me from your videos and hard work.
Sometimes I just come to this channel to watch things catch on fire. And thanks to a good chemistry teacher in High School, I can actually understand all (well, most) of the steps. Too bad I am a complete klutz around dangerous chemicals and would probably burn my house down if I try any of the videos involving fire.
JayMark2049 true, I'm the same way. however its the profession attributed to understanding this so thats why i suggested. and 001100AAAEA whats so bad about being a chemist?
+Akatosh x I love math and physics but I hate chemistry for some reason... it's too hard for me I guess!!! (Notice that I said "me", it could be easy for you idk)
Although I'm not planning on majoring in chemistry, it's always been pretty nifty to me and your videos are always really intriguing. I've been a fan for years. :)
Also, Iron(III) complexes with oxalate, to the extent that oxalate salts will act as rust removers and you can crystallize out (exceedingly soluble) double oxalates from solution.
Better to take 5 gems ferrous oxalate and heat this in a large test tube then when fully heated cap the contents with a cork dipped in molten paraffin and allow to cool. These test tubes can be kept safe in cushioned containers for over a year and taken out of the box and you can remove the cork while pouring out the iron powder once it hits the wax the iron ignites !!
I'm not a scientist, chemist or any ist. BUT I ALWAYS ENJOY YOUR VIDS. 50 YEARS AGO WISH YOU HAD BEEN MY SCIENCE TEACHER, COZ I ALWAYS LIKED THE SUBJECT, BUT MY SCIENCE TEACHER WAS A BORING SOD AND ONLY WANTED US TO KILL STUFF OR CUT UP EYE BALLS! IF HE WEREN'T GETTING US TO LOOK THROUGH HIS REFACTOR TELESCOPE! NICE BLOKE THOUGH.
Is it possible to make one big chunk of the pyrophoric iron so that you would have a chuck of iron glowing red hot for a decent period of time? Like from the movie upside down...
Here's a little trick for you; I don't know what you use for editing, but try to find a noise cleaner. The noise isn't the sound, but the image. It's to clean most of those little spots when the room becomes darker. Or you can also invest in a 20'000$ camera, up to you.
I've been subbed for ages and usually have no idea what you're going on about yet for some reason I always enjoy these videos. Lol there is something wrong with me. :p Pretty experiments!
+KnightKiller1000 Depends if you want the putty afterwards. The putty can be thinned with organic solvents and heating and the iron left to settle out.
Would it be possible to somehow prepare this in a vial and use it as a means of starting a fire in a survival kit? Or is it too reactive to store for long periods of time.
+Gareth Dean Im interested in the science and if it can be made through different methods. im sure there are places with the info but nurdrage has the best home chemistry videos on RUclips.
Funny enough you can do this with almost any metal, oxygen is almost as reactive as fluorine, we just don’t see it, because it often forms tough passivation layers.
+NurdRage can you make a video about how to synthesize your own oxalic acid like did with hydrochloric acid and also i don't have a blowtorch is there anything else I can use
Could you use finer iron like iron wool for a faster reaction, I am looking to make bulk quantities and got 10 lbs of iron wool on Ebay for $5, they priced the listing wrong .
how do you tell by looking at the elements charts which metals will spontaneously combust in air with fine enough particle size? i know iron does and so will aluminum.
It would be better to first make a solution of oxalic acid. When one of the products is solid, you don't really want the reactant to be solid because its crystals will get caked with the product. That way you get particles of oxalic acid encased in iron(II) oxalate. Slowly dripping concentrated oxalic acid solution into a suitable solution of iron(II), while mixing it, will produce a very fine and reasonably pure product.
This process should also work with H2SO4, correct? Is my thinking correct that the acid could be poured off after iron oxalate recovery and used over and over again to make a pipeline of iron to iron oxalate? I suppose one would need to always ensure an excess of iron vs oxalic acid to prevent oxalate formation in the primary dissolution bath.
Would the direct reaction between an oxalic acid solution and iron be possible? I guess the main problem would be the precipitation of iron(II) oxalate on the surface of the nail which would slow down the reaction.
Hey NurdRage mix this pyroforic iron with Aluminium oxide will it spontaneously react wit the aluminium oxide or will it react only if it is exposed to air if the second case occurs than you have pyrophorik termite
I'm no expert on physics or chemical reactions, but my guess it would ignite no matter the temperature. Oxygen is extremely volatile, and as liquid even more than in gas form.
can you make ferrous sulfate into sulphuric acid? I heard it was doable by heating it up to decomposition temperatures (I'm unsure how high) and at which point it would produce sulphur dioxide and sulphur trioxide- which could be condensed and further processed into sulphuric acid. I was really hoping you could.confirm or debunk this.
Kane Rhodes yes, you can. Old chemists did this to obtain sulphuric acid, back in 1800. They decomposed it in FeO and SO3, and then absorbed the SO3 in water. The downside of this process is that it deals with SO3. When it comes in contact with air it instantly soaks up any water present and creates a heavy sulphuric acid fog. This reaction is also pretty violent. This is quite dangerous, and i would not recommend doing that.
So, if this would make good thermite, and he is using it on aluminum foil, could it happen that the reaction of the hot iron oxide and aluminum foil could start the thermite reaction and continue, if there was enough aluminum?
Nice video NR :)) So other day I was making an Iron oxalate and when I started heating the beaker (containing FeSO4 and oxalic acid). Then some Iron oxalate precipitate and created a few little bangs in the beaker (I thought that my beaker will explode). Why it happened to me? Is there any scientific explanation of this? BTW sorry for my bad English.
Hello, NurdRage. Nice Pyrophoric Iron video. I wonder if you can make Iron (II) Oxalate using Iron Carbonates and Hydroxides And Oxalic Acid Dihydrate........
Sup3rman1c Oh thanks. I guess I will just wait for high school. One more year and I will be 15 and go to a high school. That is why I want to know. Schools in Europe are at 15years and above (high schools). And I really love chemistry. But still thanks.
@@RobertSzasz But as that reacts to form the iron oxide and provides a fairly high temp when it does the conversion, then it would have the heat and the Iron Oxide fe2 from that Pyrophoric Iron and would maybe continue with the thermite reaction once the correct aluminum/iron oxide ratio is reached? I am not a chemist so I may just not be getting it, but it just seems like it should flow along if the end result of the PI is fe2 and just would need aluminum and heat to go thermite.
@@peregrine1970 oxygen doesn't penetrate solids or piles of powder well. The reason thermite works is that the iron oxide and aluminium are well mixed together and iron oxide feeds oxygen to the aluminum.
NurdRage, Referring to an article recently published in the Royal Soc. Chem's sister publication, 'Chemistry World', titled: "Environmentally Friendly Quantum Dots Make Their Mark", maybe you would like to synthesise indium phosphide nanoparticles?
NurdRage I'm not good when it comes to chemestry so I am unsure. I believe when I was in chemestry class in h.s I was told always use distilled water.... I just wanted to make sure that is what your suppose to use for people like me who are unsure. In your video you said wash it down with water.... Thank you for your feedback :)
Many chrome salts have a nice dark green, but also other colors. And I think the salts of Cobalt have many colors ranging from blue to red, also purple. Manganese is also quite colorful. Permanganates have a very intense purple color but the Manganese salts can also be green, brown and slightly pinkish. Transition metals in general produce any kind of imaginably colored salts.
1. I'm glad you have a glassware sponsor!
2. As someone who is hearing impaired, I especially appreciate that you caption your videos!

Where is the link?

+NurdRage I hope you have a good time. I love your videos :)
+NurdRage Could you use a bunsen or lab burner in place of a propane torch when converting the Ferrous Oxalate to the Pyrophoric Iron? Great Video!
Have a good time with your family.
+NurdRage You took my advice to make pyrophoric iron. Nice! :D
if you do make daraprim, could you somehow switch the chlorine with another halogen and possibly make a new drug altogether?
I've been fascinated with this video for a while now and I've been working on making this myself. I thought I had done something wrong earlier because I was just left with a brown solution after adding the iron chloride to the oxalic acid even after it had completed cooled.

You're a bright spark to come up with this method.
These are the most interesting videos that I don't understand.
then become a chemist
+Akatosh x You don't need to be a chemist to understand these reactions. :)
+Akatosh x fuck that
JayMark2049 true, I'm the same way. however its the profession attributed to understanding this so thats why i suggested.
and 001100AAAEA whats so bad about being a chemist?
+Akatosh x I love math and physics but I hate chemistry for some reason...
it's too hard for me I guess!!!
(Notice that I said "me", it could be easy for you idk)
Wow. I learned something. Never seen this experiment before. Well done.
+NurdRage 1:20 Yeah, the only thing I remember from grade school chemistry was "do as you ought'r, add acid to water." Thanks for the memories!
This is one of my favourites! I've made it somewhat often back then, because it looks so nice :)
I have no means or desire to do any of these experiments, but i love chemistry and i love watching your videos :-)
Although I'm not planning on majoring in chemistry, it's always been pretty nifty to me and your videos are always really intriguing. I've been a fan for years. :)
Note: FeC2O4 may not precipitate at 2:55 due to low Ph. It will work better if you use ammonium or sodium oxalate in place of oxalic acid.
Wow, that ferrous oxalate is a beautiful shade of yellow.
Omg simply amazing!
Also, Iron(III) complexes with oxalate, to the extent that oxalate salts will act as rust removers and you can crystallize out (exceedingly soluble) double oxalates from solution.
3:25 yes !!! From pcb chemical
Great for hand warmers too.

These test tubes can be kept safe in cushioned containers for over a year and taken out of the box and you can remove the cork while pouring out the iron powder once it hits the wax the iron ignites !!
wow that is wild! never knew iron could spontaneously combust...
Where can I get the bongs that I see in this video?
Links in the doobilydoo
lol
Mazekwon you watch too much AvE bruh

Great video!
Oh yes, I love pyrophoric substances.
Is it possible to make one big chunk of the pyrophoric iron so that you would have a chuck of iron glowing red hot for a decent period of time? Like from the movie upside down...
can we make aluminium powder for flash powder like this ?
When it's done burning, it looks like an inside of a hand warmer when it's not warm anymore.
U can use FeSO4 instead of FeCl2, work as well ;)
Can you simulate Mark Watney's hydrazine into water experiment? :)
Gian Carlo Martinelli no, ci tiene alla sua pelle.
Omg wow this is so cool it gave me more info in my brain
Here's a little trick for you;
I don't know what you use for editing, but try to find a noise cleaner.
The noise isn't the sound, but the image. It's to clean most of those little spots when the room becomes darker.
Or you can also invest in a 20'000$ camera, up to you.
What does he say at 5:12? It sounds like the audio cuts out for a moment.
NurdRage, The Iron was generating hydrogen BEFORE the heating and the stirring.
I've been subbed for ages and usually have no idea what you're going on about yet for some reason I always enjoy these videos. Lol there is something wrong with me. :p Pretty experiments!
Why do you use gravity filtration? Why not Buchner funnel (vacuum filtration)?
I'm wondering if there is a way to extract iron from "Thinking Putty?" If so could you do a video about it.
That would be super cool.
+KnightKiller1000 Depends if you want the putty afterwards. The putty can be thinned with organic solvents and heating and the iron left to settle out.
Chemistry is so cool. I totally missed out.
Could you make a large batch of this and then make a video of you testing it in thermite?
you should make candy rocket with different additives with pure substances and how to make them
in the next video you should teach us how to wear proper safety protocols
Would it be possible to somehow prepare this in a vial and use it as a means of starting a fire in a survival kit? Or is it too reactive to store for long periods of time.
I think that it would be suitable to store in a vacuüm.
Doesnt help, since it reacts with itself like said in the video.
cool video. do you have any videos on making iodine or hydrogen peroxide?
+nickwoo2 You'd be better off buying peroxide than making it. Stuff is persnickety.
+Gareth Dean Doesn't mean we don't wanna see the process!
+Gareth Dean Im interested in the science and if it can be made through different methods. im sure there are places with the info but nurdrage has the best home chemistry videos on RUclips.
*****
Good point. I myself think its production is rather dull, mostly electrolysis of clear solutions.
Gareth Dean
A lot of inorganic chemistry is "dull" like that. At least it's not asking to work with azidoazide azides!
+NurdRage can you please do a video about making potassium chlorate with electrolysis?
Funny enough you can do this with almost any metal, oxygen is almost as reactive as fluorine, we just don’t see it, because it often forms tough passivation layers.
It's superparamagnetic I'm sure. Move a magnet close to it to see particles moving.
+NurdRage can you make a video about how to synthesize your own oxalic acid like did with hydrochloric acid and also i don't have a blowtorch is there anything else I can use
do you synthesize your own reagent grade chemicals or do you purchase them? and of so, what website do you recommend for glassware and or chemicals
maybe something more about pyrophoricity? Do you have the equipment to perform some experiments on metalorganics like BuLi or grignard-compounds?
Could you use finer iron like iron wool for a faster reaction, I am looking to make bulk quantities and got 10 lbs of iron wool on Ebay for $5, they priced the listing wrong .
Magic!
how do you tell by looking at the elements charts which metals will spontaneously combust in air with fine enough particle size? i know iron does and so will aluminum.
Where did u get the reflux condenser and how does it work?
I know that using mag stirring seems like a great idea, but it has to scratch the hell out of your flask.
WHO IS READY FOR THE SUPERMOON!!!!!!!!!1 WOOOOOOOOOOOOOOOOOOOOOOOOOOOO
What kind of iron is used in hand warmers
It would be cool if you can show a video of silver plating. Not silver nitrate on copper like all the other silver plating videos on you tube.
During the end when you dumped it, how hot was it burning at?
I keep trying to read "Oxalate" as a hexadecimal number when I first see it.
254 + 662142 = 16695812
Chemistry has a bug.
+frtard
XD
+timewave02012 0xa1a7e
Where do the 254 and 16695812 come from?
Would that produce the fine iron needed to make magnetic ferrofluid?
is the end result useful for nickel iron batteries?
It would be better to first make a solution of oxalic acid. When one of the products is solid, you don't really want the reactant to be solid because its crystals will get caked with the product. That way you get particles of oxalic acid encased in iron(II) oxalate.

I suppose one would need to always ensure an excess of iron vs oxalic acid to prevent oxalate formation in the primary dissolution bath.
2:50 And you use drain cleaner sulfuric acid XD
I don't have Ferrous Chloride. Will Ferrous Bueller do?
How would you feel about making some super-fluid helium?
Since grinding dust is iron that's been burnt and thus some form of iron oxide, would it be possible to make thermite with it?
Would the direct reaction between an oxalic acid solution and iron be possible? I guess the main problem would be the precipitation of iron(II) oxalate on the surface of the nail which would slow down the reaction.
if you were to add the aluminium under an inter athmosphere woud you get a self igniting thermite?
Hey NurdRage mix this pyroforic iron with Aluminium oxide will it spontaneously react wit the aluminium oxide or will it react only if it is exposed to air if the second case occurs than you have pyrophorik termite
would it still ignite like that if it was cold?
+engelteir Yes, it reacts to oxygen.
+Lord Shagrax The activaton energy might be too low, if it was at room temperature :P
i was thinking it might just rust or something like that, maybe quickly. but not actually combust.
I'm no expert on physics or chemical reactions, but my guess it would ignite no matter the temperature. Oxygen is extremely volatile, and as liquid even more than in gas form.
+Lord Shagrax You don't understand what volatile means then.
Is it possible to create large crystals of magnetite to demonstrate its magnetic strength?
is there any way to store this pyrophoric iron for later use??
So, can this melt steel beams?
Can you use this to make thermite
Can this process work with other iron salts?
Cool!
Is that an Extreme Q mini whip I see at 4:58? If not, that's uncanny...
can you make ferrous sulfate into sulphuric acid?
I heard it was doable by heating it up to decomposition temperatures (I'm unsure how high)
and at which point it would produce sulphur dioxide and sulphur trioxide- which could be condensed and further processed into sulphuric acid.

This reaction is also pretty violent. This is quite dangerous, and i would not recommend doing that.
What would happen if you mixed this with aluminum? Would it create spontaneous thermite?
Can we use extemely fine powder of iron carbonatae
How do you know that your iron oxide is more pure than the laboratory grade one?
You said that the resulting iron oxide is pure. Does that mean that the magnetite that was present has also been converted to iron oxide?
Awesome
So, if this would make good thermite, and he is using it on aluminum foil, could it happen that the reaction of the hot iron oxide and aluminum foil could start the thermite reaction and continue, if there was enough aluminum?
I was wondering something similar. If you mixed with an aluminum power if it would make self-ignorating thermite
Is it possible to make pyrophoric iron by displacing it from solution of iron sulfate with other metal like aluminium?
no, because the Aluminium poisons the iron surface, but you are right in thinking that it could do that...but not in this case.
Zinc or Magnesium maybe?
Nice video NR :)) So other day I was making an Iron oxalate and when I started heating the beaker (containing FeSO4 and oxalic acid).

Hello, NurdRage. Nice Pyrophoric Iron video. I wonder if you can make Iron (II) Oxalate using Iron Carbonates and Hydroxides And Oxalic Acid Dihydrate........
How do you know that your acid is 10M. I buy mine HCl (31%) as a special drain cleaner but it doesnt say rhe molarity.
Sup3rman1c Oh thanks. I guess I will just wait for high school. One more year and I will be 15 and go to a high school. That is why I want to know. Schools in Europe are at 15years and above (high schools). And I really love chemistry. But still thanks.
be great to have sealed ampules of that for camping...
Kinda makes me wonder. If you keep it in say an argon atmo, then add in the aluminum powder and then expose to oxygen. Self-igniting thermite?
No, you need the metal oxide to react with the aluminum
@@RobertSzasz But as that reacts to form the iron oxide and provides a fairly high temp when it does the conversion, then it would have the heat and the Iron Oxide fe2 from that Pyrophoric Iron and would maybe continue with the thermite reaction once the correct aluminum/iron oxide ratio is reached?

NurdRage,
Referring to an article recently published in the Royal Soc. Chem's sister publication, 'Chemistry World', titled: "Environmentally Friendly Quantum Dots Make Their Mark", maybe you would like to synthesise indium phosphide nanoparticles?
Idle curiosity: Is there a physics imposed limit on how fine iron oxide can become? (as in, a physical limit greater than one molecule)
Fantastic, fun not enraging at all :)
would this work with FeCl3?
Damn that's fucking awesome! I really need youtube channels like yours.! Informative video ftw!.
would this work with aluminum instead of iron
No
Shouldn't you always wash down with distilled water?
+Aaron orourke I don't think i said not to.
NurdRage I'm not good when it comes to chemestry so I am unsure. I believe when I was in chemestry class in h.s I was told always use distilled water....

If cooper salts are blue, iron salts are yellow, then what metals have salts that are red? green? maybe even purple?
Many chrome salts have a nice dark green, but also other colors.
And I think the salts of Cobalt have many colors ranging from blue to red, also purple.
Manganese is also quite colorful. Permanganates have a very intense purple color but the Manganese salts can also be green, brown and slightly pinkish.
Transition metals in general produce any kind of imaginably colored salts.
Mmm ... I wonder who turned off the light's ??
