[{"from": "human", "value": "What can you tell me about this molecule? [N+1][=Branch1][C][=O][Branch1][C][O][O-1]"}, {"from": "gpt", "value": "The molecule is a highly corrosive mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercially available nitric acid has a concentration of 68%. When the solution contains more than 86% HNO3, it is referred to as fuming nitric acid. Nitric acid is the primary reagent used for nitration - the addition of a nitro group, typically to an organic molecule. The main industrial use of nitric acid is for the production of fertilizers. Nitric acid is neutralized with ammonia to give ammonium nitrate. The other main applications are for the production of explosives, nylon precursors, and specialty organic compounds."}]
