  2. Vanadium(V) oxide - Wikipedia

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

    Vanadium(V) oxide serves the crucial purpose of catalysing the mildly exothermic oxidation of sulfur dioxide to sulfur trioxide by air in the contact process: 2 SO 2 + O 2 ⇌ 2 SO 3 The discovery of this simple reaction, for which V 2 O 5 is the most effective catalyst, allowed sulfuric acid to become the cheap commodity chemical it is today.

    en.wikipedia.org/wiki/Vanadium_oxide

    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 2 O 3. [1] Called Magnéli phases for Arne ...

    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 ...

  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 ...

  6. Vanadium - Wikipedia

    en.wikipedia.org/wiki/Vanadium

    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

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

    In the Vanadium(V) oxide#Sulfuric acid production section, the equation :SO 2 + V 2 O 5 → SO 3 + 2VO 2 seems to be missing a few oxygen atoms. Would someone please fix it or explain the apparent four missing atoms? Thanks Jim1138 00:12, 29 April 2012 (UTC) You have one sulfur, 7 oxygen, and 2 vanadium atoms on the left hand side.

  8. Vanadyl perchlorate - Wikipedia

    en.wikipedia.org/wiki/Vanadyl_perchlorate

    Vanadyl perchlorate or vanadyl triperchlorate is a golden yellow coloured liquid or crystalline compound of vanadium, oxygen and perchlorate group. The substance consists of molecules covalently bound and is quite volatile; it ignites organic solvents on contact and explodes at temperatures above 80 °C.

  9. Sodium orthovanadate - Wikipedia

    en.wikipedia.org/wiki/Sodium_orthovanadate

    Sodium orthovanadate is produced by dissolving vanadium(V) oxide in a solution of sodium hydroxide: V 2 O 5 + 6 NaOH → 2 Na 3 VO 4 + 3 H 2 O. The salt features tetrahedral VO 3− 4 anion centers linked to octahedral Na + cation sites. [3]
