In this video we make nitric acid by reacting calcium nitrate with oxalic acid.
The process is rather simple, dissolve 300g of Calcium Ammonium Nitrate (A common fertilizer) in 1L of water and then dissolve 150g of Oxalic Acid dihydrate in 300mL of water with heating. Then mix the two. A white precipitate of calcium oxalate is formed. Filter this off and distill the filtrate. The distillate will be dilute nitric acid. Fractionally distill that to get azeotropic nitric acid. The yield is around 74%

TYy…. yet I would simply buy it! Greetings from an M. Sc. of chemistry….😉
Will this work with H3PO4 and Ca|NO3|2? are the Ca salts of H3po4 easy enough to handle?
This works great for me as I’ve got 20kg of calcium nitrate, and probably close to that amount of oxalic acid
I'm very late on this video, wouldn't it be possible to do something similar with an acidic ion exchage resine ?
Those can be regenerated to.
Chinese fans love your chemistry videos very much, but the videos on bilibili have not been updated for a long time. Can I transfer your series of videos to the Chinese website "acfun" or "bilibili"? I will write the YouTube channel address. I will not use it to make money. Thank you
Can anyone help out? I have an aqueous solution of Pb(NO3)2. Through electrolysis all of the Pb was combined into PbO2. Now does that means the NO3 ions are still in the solution and can i add oxalic acid to produce HNO3 and oxalate? And then carry out the procedure above?
Nitric acid from rhubarb leaves. Sounds good to me…

This is great! Can we recover oxalic from calcium oxalate? The fact it precipitated from a moderate strength nitric acid does not give hope. But make calcium oxalate can react with hydrochloric acid
I wonder how hard it would be to get enough oxalic acid from wood sorrel to get enough for this
