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%

You are absolutely the best
I checked with ChatGPT and you can use hydrochloric acid (HCl) to convert calcium oxalate back into oxalic acid. HCL should be pretty easy to make at home with electrolysis.
Is there any easy way to recover Oxalic acid back from CaC2O4 ?
Man watching the precipitate just appear like that was mesmerising
How useful. !!
Thanks. Have you heard anything about Elemental Maker? I haven't seen him post anything in ages. I enjoy your content!
I wonder how acidic and oxidizing a hot concentrated mixture/solution of calcium nitrate and oxalic acid can be.
Maybe one can use it as crude concentrated nitric acid for etching and other applications!?
Yet, oxalic acid is hardly cost effective in comparison with bisulfate, as you probably won't recover the oxalic acid from the oxalate waste. Only then it would have an advantage imho, but you would probably need/use sulfuric acid then anyways.
I wonder if ammonium sulfate would work
good to have you back !!
Sir this was really awesome procedure and honestly I didn't expect that will end like this. Extremally helpful tnx 🙂
