Cerium(IV) selenate explained

Cerium(IV) selenate is an inorganic compound with the chemical formula Ce(SeO₄)₂.

Preparation

Cerium(IV) selenate can be obtained by reacting cerium(IV) hydroxide with hot selenic acid, and the tetrahydrate can be crystallized from the solution.^[1]

Properties

Cerium(IV) selenate has a space group of Pbca, and its unit cell parameters are a = 9.748 Å, b = 9.174 Å, and c = 13.740 Å.^[2]

It hydrolyzes when exposed to water and can be reduced to trivalent cerium using hydrogen peroxide.^[3]
