    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. Examples of these phases include V 3 O 7, V 4 O 9 and V 6 O 13. [1] Phases with the general formula V n O 2n−1 exist between VO 2 and V ...

  3. Vanadium compounds - Wikipedia

    en.wikipedia.org/wiki/Vanadium_compounds

    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 the +5 oxidation state.

  4. 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.

    Vanadium(V) oxide is a catalyst in the contact process for producing sulfuric acid. Vanadium compounds are used extensively as catalysts; [83] Vanadium pentoxide V 2 O 5, is used as a catalyst in manufacturing sulfuric acid by the contact process [84] In this process sulfur dioxide (SO 2) is oxidized to the trioxide (SO

  6. Vanadium(II) oxide - Wikipedia

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

    Vanadium(II) oxide is the inorganic compound with the idealized formula VO. It is one of the several binary vanadium oxides. It adopts a distorted NaCl structure and contains weak V−V metal to metal bonds. VO is a semiconductor owing to delocalisation of electrons in the t 2g orbitals.

  8. Vanadium(IV) oxide - Wikipedia

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

    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]

  9. 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 ...
