Peroxynitric acid or peroxonitric acid is a
chemical compound with the
formula HNO
4. It is an
oxyacid of nitrogen, after
peroxynitrous acid.
Peroxynitrate, the conjugate base of peroxynitric acid, is formed rapidly during decomposition of peroxynitrite in neutral conditions. [4]
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]
