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 + O2 + 2 H2O
The energy given off is sufficient to form ozone from diatomic oxygen:
- 3 O2 (g) → 2 O3 (g)
Salts containing the deprotonated anion XeO2−4 are presently unknown.[3]
