Strontium Metavanadate, SrV₂O₆.4H₂O

Strontium Metavanadate, SrV₂O₆.4H₂O, is prepared as a faintly yellow, powdery precipitate by the action of the normal potassium salt on strontium chloride. It loses 2 molecules of water over sulphuric acid, and the rest at 280° C., when it melts to a brown glass.

A number of acid salts have been obtained, which, on treatment with water, give the normal salt. There are also some double strontium potassium acid salts.
