These solutions contain mainly the ions HVO 4 2− and V 2 O 7 4− between pH 9 and pH 13, but below pH 9 more exotic species such as V 4 O 12 4− and HV 10 O 28 5− (decavanadate) predominate. Upon treatment with thionyl chloride, it converts to the volatile liquid vanadium oxychloride, VOCl 3: [11] V 2 O 5 + 3 SOCl 2 → 2 VOCl 3 + 3 SO 2

Vanadium(IV) oxide or vanadium dioxide is an inorganic compound with the formula VO 2.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]
