The molecular formula isHNOthree

Physicochemical properties: pure nitric acid is a colorless fuming liquid, and the general commodity is slightly yellow. Nitric acid is irritant and unstable. It will decompose and release nitrogen dioxide when exposed to light or heat. densityone.5027（25℃）、沸点8three℃、冰点-42℃。能与水于任何比例混合。浓Nitric acid is highly corrosive. It will burn if it touches the skin, and can also damage the mucous membrane and respiratory tract. It is a strong oxidant, which can cause combustion when mixed with organic matter and sawdust.
