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]

HO
2NO
2 ⇌ HO•
2 + NO•
2
