Cadmium selenate explained

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.

Properties

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