Xenic acid is a proposed noble gas compound with the chemical formula H2XeO4 or XeO2(OH)2. It has not been isolated, and the published characterization data are ambiguous.[2]

Salts of xenic acid are called xenates, containing the HXeO
4
anion, such as monosodium xenate. They tend to disproportionate into xenon gas and perxenates:[3]

2 HXeO
4
+ 2 OH
XeO4−
6
+ Xe + O
2
+ 2 H
2
O

The energy given off is sufficient to form ozone from diatomic oxygen:

3 O
2
(g) → 2 O

(g)

Salts containing the deprotonated anion XeO2−
4
are presently unknown.[3]
