The vanadate ion, represented as VO4^3-, is a polyatomic ion containing vanadium in its +5 oxidation state. It consists of one vanadium atom surrounded by four oxygen atoms arranged in a tetrahedral geometry. Vanadate is commonly found in various minerals and can be produced through the oxidation of vanadium compounds. Vanadate ions are of interest in several fields, including biochemistry and materials science. They can act as enzyme inhibitors and are studied for their potential effects on metabolism. Additionally, vanadate compounds are used in the synthesis of catalysts and other chemical applications.
