Vanadium (IV) solution. Solution that contains (VO)2+ ions. It was obtained by reducing ammonium metavanadate (V) (NH4VO3) using zinc amalgam as a catalyst. Vanadium can exist in four adjacent oxidation states (2-5) that produce solutions of different colours. Here vanadium is in the +4 oxidation state and the colour is blue. | |
