Preparation
editcaesium selenate can be obtained from the reaction of caesium carbonate and selenic acid solution:[2]
caesium selenate can also be prepared by the neutralization reaction of selenic acid and caesium hydroxide:[1]
Properties
editcaesium selenate can precipitate compounds such as CsLiSeO4·1⁄2H2O and Cs4LiH3(SeO4)4 in Cs2SeO4-Li2SeO4-H2O and its acidification system.[2] It can also form double salts with other metals, such as Cs2Mg(SeO4)2·6H2O, Cs2Co(SeO4)2·6H2O, etc.[3]
