Chemical compound

Peroxynitric acid or peroxonitric acid is a chemical compound with the formula HNO
4
. It is an oxyacid of nitrogen, after peroxynitrous acid.

Preparation

Peroxynitrate, the conjugate base of peroxynitric acid, is formed rapidly during decomposition of peroxynitrite in neutral conditions.[4]

Atmospheric chemistry

Peroxynitric acid is formed in the atmosphere, although it is unstable, it is important as a reservoir for NO2 through the reversible radical reaction:[5]
