Physical properties of Sodium tungstate: (1)H-Bond Donor: 0; (2)H-Bond Acceptor: 4; (3)Rotatable Bond Count: 0; (4)Exact Mass: 293.91013; (5)MonoIsotopic Mass: 293.91013; (6)Topological Polar Surface Area: 80.3; (7)Heavy Atom Count: 7; (8)Formal Charge: 0; (9)Complexity: 62.2; (10)Covalently-Bonded Unit Count: 3.

Preparation: this chemical can be prepared by tungsten trioxide and sodium carbonate.

Sodium tungstate, a tungstate of sodium, is useful as a source of tungsten. It is prepared from tungsten ores used to manufacture tungsten by reducing it. It is also thought to be a possible inhibitor of protein-tyrosine phosphatase. It is also sometimes used as a fireproofing agent. In organic chemistry, sodium tungstate is used as catalyst for epoxidation of alkenes and oxidation of alcohols into aldehydes or ketones.
