'''Monosodium xenate''' is the [[sodium salt]] of [[xenic acid]] with formula NaHXeO<sub>4</sub>. It is a powerful [[oxidizer]], owing to being a highly [[reactivity (chemistry)|reactive]] compound of xenon.<ref>{{cite journal|last1=Peterson|first1=Jeffrey L.|last2=Claassen|first2=Howard H.|last3=Appelman|first3=Evan H.|title=Vibrational spectra and structures of xenate(VI) and perxenate(VIII) ions in aqueous solution|journal=Inorganic Chemistry|date=March 1970|volume=9|issue=3|pages=619–621|doi=10.1021/ic50085a037}}</ref>

== Synthesis ==
Monosodium xenate can be made by mixing solutions of [[xenon trioxide]] and [[sodium hydroxide]], followed by freezing to [[liquid nitrogen]] temperatures, and dehydrating in a vacuum.<ref name=max/>

==Properties==
Monosodium xenate usually exists in the sesquihydrate form, with 1.5 waters of hydration per unit molecule. It is stable up to 160&nbsp;°C heated in a pure state.  However it can explode when subjected to mechanical shock, or lower temperatures when mixed with XeO<sub>3</sub>.<ref name=max/>
Sodium xenate is slightly toxic with a median lethal dose between 15 and 30&nbsp;mg/kg of body weight in mice. Xenate leaves the body very quickly.  In mice, the level in blood drops by half in twenty seconds due to it being decomposed and exhaled. In the peritoneum the half-life extends to six minutes.<ref>{{cite web|last1=Finkel|first1=A.

The dialkali xenates XeO<sub>4</sub><sup>2-</sup> have not been discovered, as xenate disproportionates in more alkaline conditions, hence it being rare to the find the dialkaline salt Na<sub>2</sub>XeO<sub>4</sub>.<ref name=max>{{cite journal|last1=Spittler|first1=T.
