Скачать или смотреть Make Nitric Acid without Sulfuric Acid by Oxalate Precipitation

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%
