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
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.[3]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
