Xenic acid is a noble gas compound formed by the dissolution of xenon trioxide in water. Its chemical structure is H2XeO4. It is a very powerful oxidizing agent, and its decomposition is dangerous as it liberates a large amount of gaseous products—xenon, oxygen, and ozone.

Its existence was hypothesized by Linus Pauling in 1933.[1] Xenic acid has been used as an oxidizing agent in organic chemistry.

Salts of xenic acid are called xenates, containing the HXeO−
4 anion. They tend to disproportionate into xenon gas and perxenates:[2]

2 HXeO−
4 + 2 OH− → XeO4−
6 + Xe + O2 + 2 H2O

Salts containing the completely deprotonated anion XeO2−
4 are presently unknown.[2]
