Palladous Selenate, PdSeO4






Palladium dissolves in selenic acid to a deep reddish brown solution which, on concentration, yields a mixture of palladous selenate and selenous acid. Pure palladous selenate, PdSeO4, results when palladium is dissolved in a mixture of selenous and nitric acids. It crystallises in dark brownish red, hygroscopic rhombs, and forms double salts with ammonium selenate or sulphate. When warmed with concentrated hydrochloric acid, chlorine is evolved.
