Chemical compound

Sodium molybdate, Na2MoO4, is useful as a source of molybdenum.[2] This white, crystalline salt is often found as the dihydrate, Na2MoO4·2H2O.

The molybdate(VI) anion is tetrahedral. Two sodium cations coordinate with every one anion.[3]

Sodium molybdate was first synthesized by the method of hydration.[4] A more convenient synthesis is done by dissolving MoO3 in sodium hydroxide at 50–70 °C and crystallizing the filtered product.[3] The anhydrous salt is prepared by heating to 100 °C.

The agriculture industry uses 1 million pounds per year as a fertilizer. In particular, its use has been suggested for treatment of whiptail in broccoli and cauliflower in molybdenum-deficient so...
