Properties
Sodium Molybdate is colorless or slight green crystal, insoluble in ethanol, the solubility in water is 40g at least in normal temperature. Sodium Molybdate can be used in the production of alkaloid, dye, fertilizer, pigment, catalyst, fire retardant, or nuisance-free metal inhibitor for cooling water system, or used in galvanized buffing compound and chemical reagents.
Usage
Sodium molybdate is used in biochemistry and medicinal chemistry to track various organic chemicals that are colorless after a chromatographical procedure, which it always stains blue. The blue color is also called molybdenum blue.
The agriculture industry uses 1 million pounds per year as a fertilizer. However, care must be taken because at a level of 0.3 ppm sodium molybdate can cause copper deficiencies in animals, particularly cattle.
Sodium molybdate is used for water treatment.
Sodium molybdate is used in industry for corrosion inhibition, as it is a non-oxidizing anodic inhibitor. The addition of sodium molybdate significantly reduces the nitrite requirement of fluids inhibited with nitrite-amine, and improves the corrosion protection of carboxylate salt fluids.
According to an article from 1950 that was published in Nature, sodium molybdate is useful for curing a broccoli disease known as ‘whiptail’.
Precautions
Sodium molybdate is incompatible with alkali metals, most common metals and oxidizing agents. It will explode on contact with molten magnesium. It will violently react with interhalogens (e.g., bromine pentafluoride; chlorine trifluoride). Its reaction with hot sodium, potassium or lithium is incandescent.
