Nitric Acid

HNO₃·63.013 g/mol·Acids·CID 944
IndustrialStrong Acid

A strong mineral acid and powerful oxidizer. Produced via the Ostwald process. Essential for fertilizer (ammonium nitrate) and explosives manufacturing. Fuming HNO₃ was used in early rocket propellants.

IUPAC: nitric acid

Also known as: 7697-37-2, Azotic acid, Aqua fortis, Salpetersaeure, Nital (+14 more)
