CAS Number: 7697-37-2 Linear Formula: HNO3 PHYSICAL PROPERTIES: strong monobasic acid. Colorless liquid fuming in air PRODUCTION: Nitric acid is one of the most large-capacity products in the chemical industry. The modern method of its production is based on the catalytic oxidation of synthetic ammonia on platinum-rhodium catalysts (Ostwald process) to a mixture of nitrogen oxides (nitrous gases), with their further absorption by water. APPLICATION: in the production of mineral fertilizers; in the military industry (fuming - in the production of explosives, as an oxidizer for rocket fuel, diluted - in the synthesis of various substances, including poisonous ones); extremely rare in photography - diluted - acidification of some tinting solutions; in easel graphics - for etching printing plates (etching boards, zincographic printing forms and magnesium clichés). in the production of dyes and drugs (nitroglycerin) in jewelry - the main way to determine gold in a gold alloy
