Vanadium(IV) oxide or vanadium dioxide is an inorganic compound with the formula VO 2. It is a dark blue solid. It is a dark blue solid. Vanadium (IV) dioxide is amphoteric , dissolving in non-oxidising acids to give the blue vanadyl ion , [VO] 2+ and in alkali to give the brown [V 4 O 9 ] 2− ion, or at high pH [VO 4 ] 4− . [ 4 ]
Toxic: a chemical that has a median lethal concentration (LC 50) in air of more than 200 parts per million (ppm) but not more than 2,000 parts per million by volume of gas or vapor, or more than 2 milligrams per liter but not more than 20 milligrams per liter of mist, fume or dust, when administered by continuous inhalation for 1 hour (or less if death occurs within 1 hour) to albino rats ...

Vanadium oxide mainly refers to: Vanadium(II) oxide (vanadium monoxide), VO; Vanadium(III) oxide (vanadium sesquioxide or trioxide), V 2 O 3; Vanadium(IV) oxide (vanadium dioxide), VO 2; Vanadium(V) oxide (vanadium pentoxide), V 2 O 5; Various other distinct phases include: Phases with the general formula V n O 2n+1 exist between V 2 O 5 and VO 2.
Vanadium pentoxide is a commercially important catalyst for the production of sulfuric acid, a reaction that exploits the ability of vanadium oxides to undergo redox reactions. [2] The vanadium redox battery utilizes all four oxidation states: one electrode uses the +5/+4 couple and the other uses the +3/+2 couple. Conversion of these oxidation ...
