Sodium molybdate
Sodium molybdate, Na2MoO4, is useful as a source of molybdenum. This white, crystalline salt is often encountered as the dihydrate, Na2MoO4·2H2O. == Structure == In aqueous solution, sodium molybdate features dissociated sodium ions and tetrahedral molybdate (MoO2−4), which adopts a sulfate-like structure.
