Sodium orthovanadate
Sodium orthovanadate is the inorganic compound with the chemical formula Na3VO4·2H2O (sodium orthovanadate dihydrate). It is a salt of the VO3−
4 oxyanion. It is a colorless, water-soluble solid.
Contents
Synthesis and structure
Sodium orthovanadate is produced by dissolving vanadium(V) oxide in a solution of sodium hydroxide:
V2O5 + 6 NaOH → 2 Na3VO4 + 3 H2OThe salt features tetrahedral VO3−
4 centers linked to octahedral Na+ sites.
Reactions
Acidification of orthovanadate induces condensation to polyoxovanadates, specifically decavanadate.
Vanadates exhibit a variety of biological activities, in part because they serve as structural mimics of phosphates.
