Selenate and telluride

Selenate and telluride

Selenite and tellurite salts (selenite and tellurite) are obtained by the action of chlorine in a solution of selenite and tellurite or by the melting of SeO2 and TeO2 with nitrate. They are strong oxidants and easy to reduce. Selenates have properties similar to sulfates, but tellurates are quite different from them.

Thus, barium BaTeO4 telluride (unlike BaSO4 and BaSeO4) is released from a solution of crystalline water and is readily soluble in hydrochloric acid.

Tellurates do not form alum salts, which also distinguishes them from selenates and sulfates.
