One Of The Most Commonly Used Digestion Reagents And Oxidants For Organic Matter Decomposition Is Concentrated Nitric Acid (HNO3)

Strong Concentrated Nitric Acid has the chemical formula HNO3. It is also referred to as aqua fortis and the spirit of niter. It has no colour while it is young but develops a yellow cast as it ages. This colour is a result of nitric acid's breakdown into nitrogen oxides and water. It is extremely poisonous and corrosive. It burns the skin badly. It forms nitrate salts when it interacts with hydroxides, metals, and oxides. A powerful oxidising agent is HNO3. It can be produced by ammonia being catalytically oxidized. It is a typical laboratory reagent and a crucial chemical in the production of fertilisers and explosives.
