Cadmium selenate is a selenate of cadmium, with the chemical formula CdSeO4.

Preparation

Cadmium selenate can be formed by the reaction of cadmium oxide and selenic acid. The product is a mixture of monohydrate and dihydrate.[4]

CdO + H2SeO4 → CdSeO4 + H2O

Properties

Cadmium selenate dihydrate is a colorless solid. At 100 °C, the dihydrate releases water of crystallization to form cadmium selenate monohydrate.[1] The monohydrate is monoclinic with space group P21/c (no. 14),[4] while the dihydrate is orthorhombic, with space group Pbca (no. 61).[5]
