Sodium orthovanadate is the inorganic compound with the chemical formula Na3VO4.2H2O (sodium orthovanadate dihydrate). It is a salt of the VO43- oxyanion. It is a colorless, water-soluble solid.[1]
Synthesis and structure
Sodium orthovanadate is produced by dissolving vanadium(V) oxide in a solution of sodium hydroxide:
- V2O5 + 6 NaOH → Na3VO4 + 3 H2O
The salt features tetrahedral VO43− centers linked to octahedral Na+ sites.[2]
Reactions
Acidification of orthovanadate induces condensation to polyoxovanadates, specifically decavanadate.[3]
Vanadates exhibit a variety of biological activity, in part because it serves as structural mimics of phosphates.[4][5]
