Caesium selenate explained

Caesium selanate is an inorganic compound, with the chemical formula of Cs₂SeO₄. It can form colourless crystals of the orthorhombic crystal system.

Preparation

caesium selenate can be obtained from the reaction of caesium carbonate and selenic acid solution:^[1]

Cs2CO3 + H2SeO4 -> Cs2SeO4 + H2O + CO2

\uparrow

caesium selenate can also be prepared by the neutralization reaction of selenic acid and caesium hydroxide:

2 CsOH + H2SeO4 -> Cs2SeO4 + 2 H2O

Properties

caesium selenate can precipitate compounds such as CsLiSeO₄·H₂O and Cs₄LiH₃(SeO₄)₄ in Cs₂SeO₄-Li₂SeO₄-H₂O and its acidification system. It can also form double salts with other metals, such as Cs₂Mg(SeO₄)₂·6H₂O, Cs₂Co(SeO₄)₂·6H₂O, etc.^[2]
