[Ferrous Oxalate Synthesis] [Pyrophoric Iron]

Why not try to neutralise the excess HCl you formed in the intermediate step?

11:20 kinda looks like u peed into the beaker lol

Great video. I rea

I really liked how you explained everything step by step.

Nice! You keep your chemicals in pickle/jam jars too. Where did you buy your H2C2O4?

@99Chemicals Yes! I buy canning jars by the 24-pack at my local supermarket. I bought the oxalic acid from skylighter(dot)com

@FPengu1n Ferrous chloride in solution is weakly acidic and therefore most stable in acidic conditions. Neutralization with a base may form an unwanted salt like ferrous hydroxide/ferrous oxide.

@98JMA you can use any soiuble iron salt

nice. simple and fun. would be cool to get a fair amount of the iron powder (~5g) in a sealed bag and use a blast of compressed air to release it. I bet it would make a nice glowing mushroom cloud at night. thanks for the vid

I used to put some iron wool in H2SO4. Retrieve some Ferrous or ferric sulfate. I read that because of the heat it turns to be ferric sulfate. I saw a vid of Ferrous sulfate in cold iced water. But the cristals looked the same to me. Tried to make some Fe2C2O2 n looks to be it. Does ferric n ferrous oxalate looks the same?? Yellow powder?

Is ferric n ferrous are pyrophoric??

Nigga u know your shit

WARNING! DON'T TURN ON THE SUBTITLE!

i like your socks

it is also in the leaves of the rubarb plant (your parents made the pie with the stocks) but the leaves have lots of oxalic acid

I'm not sure there's any "reaction" needed for the second step. ferrous chloride is almost entirely ionized in solution, whereas the oxalic acid is partially singly ionized, and much less doubly ionized. The ferrous oxalate is separated by precipitation, but this requires doubly ionized oxalic acid. Any excess hcl will reduce the ionization of the oxalic acid, so the heating both removes the hcl and also increases the ionization of the oxalic acid, no?

This looks like something I should try on a weekend...I know that some polishing powder in Walmart (Bar Keeper's Friend, or something like that) contains oxalic acid...would it be useable for this experiment, or is it suitable in quality for any experiment that needs oxalic acid, for that matter?

Hello.. :) Great video !
I tried (and succeeded?) to make magnetite Fe3O4 for ferrite cores using this method, but I think my steel wool was made of stainless steel.. When dissolved in HCl it turned very dark green, I wondered about this and concluded that it must be Chromium Chloride mixed into the Ferric Chloride.
Do you (or anybody) know if the Oxalic acid would react with the Chromium Chloride to form solid Chromium Oxalate ? (EDIT: I missed the solubility table on Wikipedia, tuns out it's soluble in water, doh)
My finished powder was bright yellow before heating, but I couldn't find any info on the color of Chromium Oxalate so I have no idea if that made it into mix :)

Ferrous oxalate didn´t precipitate upon the addition of oxalic acid because it´s soluble in acidic solutions, that´s why you need to boil the solution to evaporate most of the acid and concentrate the solution. 

Actually when you decompose ferrous oxalate, you will end up with ferrous oxide (FeO) which is unstable and disproportionates into iron metal (Fe) and magnetite (Fe3O4)!

This are the reactions: 1º - FeC2O4 * 2 H2O = FeO + CO + CO2 + 2 H2O
2º - 4 FeO = Fe + Fe3O4

So can we use iron carbonate?

I'm not a chemist nor do I want to be one. But I am however mesmerized by chemistry. In fact, I just ordered 4 books on the subject. What uses does Ferrous Oxalate have or what function does it serve? Aside from pyrotechnics, what are some other cool chemistry uses? I know it's all around us in the world we live. I just want to hear from you guys.

So, for years I have been mixing hydrochloric acid with oxalic acid to dissolve iron ore off of gemstones(my mother likes to make jewelry from raw gems). Is this what that yellowish brown sludge at the bottom of the container was?

that was anticlimactic.

Looking at the chemistry of oxalic acid....or even sugars....the krebs cycle ...... the more the CO2-reduction politics appears a fools errand.
