Description
A colorless, viscous, strongly oxidizing liquid that turns yellow with age or light exposure due to the formation of nitric oxides. Nitric acid is sold in concentrations ranging from >90% (fuming) down to 36%. The commercial reagent grade of nitric acid used in most labs contains 70% nitric acid in water. Nitric acid will dissolve most metals. It is used in the manufacture of Ammonium nitrate for fertilizer and explosives. It is also used for metallurgy, photoengraving, etching Steel, and the synthesis of dyes and polymers.
Synonyms and Related Terms
