    From left: [V(H 2 O) 6] 2+ (lilac), [V(H 2 O) 6] 3+ (green), [VO(H 2 O) 5] 2+ (blue) and [VO(H 2 O) 5] 3+ (yellow).. Vanadium compounds are compounds formed by the element vanadium (V). The chemistry of vanadium is noteworthy for the accessibility of the four adjacent oxidation states 2–5, whereas the chemistry of the other group 5 elements, niobium and tantalum, are somewhat more limited to ...

  3. Vanadium phosphates - Wikipedia

    en.wikipedia.org/wiki/Vanadium_phosphates

    Reduction of this compound with alcohols gives the vanadium(IV) phosphates. These compounds are catalysts for the oxidation of butane to maleic anhydride . A key step in the activation of these catalysts is the conversion of VO(HPO 4 )•0.5H 2 O to the pyrophosphate (VO) 2 (P 2 O 7 ).

  5. Group 5 element - Wikipedia

    en.wikipedia.org/wiki/Group_5_element

    Vanadium forms oxides in the +2, +3, +4 and +5 oxidation states, forming vanadium(II) oxide (VO), vanadium(III) oxide (V 2 O 3), vanadium(IV) oxide (VO 2) and vanadium(V) oxide (V 2 O 5). Vanadium(V) oxide or vanadium pentoxide is the most common, being precursor to most alloys and compounds of vanadium, and is also a widely used industrial ...

    In chemistry, a phosphide is a compound containing the P 3− ion or its equivalent. Many different phosphides are known, with widely differing structures. [ 1 ] Most commonly encountered on the binary phosphides, i.e. those materials consisting only of phosphorus and a less electronegative element.

  8. Vanadium(V) oxide - Wikipedia

    en.wikipedia.org/wiki/Vanadium(V)_oxide

    Vanadium(V) oxide (vanadia) is the inorganic compound with the formula V 2 O 5. Commonly known as vanadium pentoxide, it is a dark yellow solid, although when freshly precipitated from aqueous solution, its colour is deep orange. Because of its high oxidation state, it is both an amphoteric oxide and an oxidizing agent.
