Information

What is Ammonium Metavanadate?

Ammonium metavanadate is a colorless and odorless solid from the group of vanadates

Ammonium metavanadate can be produced by an ion exchange reaction of sodium metavanadate with ammonium chloride.

Ammonium metavandate is a colorless solid in the pure state, which is sparingly soluble in water, ethanol and ether, but easily soluble in dilute ammonia. The color changes to yellow as soon as it contains more vanadium(V)oxide V2O5 than corresponds to the stoichiometry. The yellowish colors are derived from polyvanadates. Aqueous solutions of ammonium metavanadate react almost neutrally. The pH value of a 5% solution at 20 °C is 6.5.

Above 50 °C it loses ammonia and easily turns into vanadium(V) oxide when heated dry

What is Ammonium Metavanadate used for?

Ammonium vanadate is used for the production of catalysts for organic and inorganic synthesis, for the production of paints and varnishes as a drying agent for paintings and inks. It is used in food analysis for the photometric determination of phosphate.
