Introduction to the formula for tungsten oxide The common oxidation state of tungsten is +6, but it exhibits all oxidation states from −2 to +6. Tungsten generally combines with oxygen to form the yellow tungstic oxide, WO 3, which further dissolves in aqueous alkaline solutions and form tungstate ions, WO 2−4. Tungsten (VI) oxide is a chemical compound that is formed from oxygen and the transition metal tungsten.
