Xenic acid is a noble gas compound formed by the dissolution of xenon trioxide in water. Its chemical formula 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 + 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 completely deprotonated anion XeO2−
4 are presently unknown.[2]
