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]
The energy given off is sufficient to form ozone from diatomic oxygen:
Salts containing the
deprotonated anion XeO2−
4 are presently unknown.
