Chemical compound
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.[1]
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:[2]
- 2 HXeO−
4 + 2 OH−
→ XeO4−
6 + Xe + O
2 + 2 H
2O
The energy given off is sufficient to form ozone from diatomic oxygen:
- 3 O
2 (g) → 2 O
3 (g)
Salts containing the deprotonated anion XeO2−
4 are presently unknown.[2]
