  2. Vanadium - Wikipedia

    en.wikipedia.org/wiki/Vanadium

    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. [23] 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 ...

  3. 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

  4. Vanadium (III) chloride - Wikipedia

    en.wikipedia.org/wiki/Vanadium(III)_chloride

    The vanadium oxides can also be used to produce vanadium(III) chloride. For example, vanadium(III) oxide reacts with thionyl chloride at 200 °C: [15] V 2 O 3 + 3 SOCl 2 → 2 VCl 3 + 3 SO 2. The reaction of vanadium(V) oxide and disulfur dichloride also produces vanadium(III) chloride with the release of sulfur dioxide and sulfur. [15]

    The most reactive metals, such as sodium, will react with cold water to produce hydrogen and the metal hydroxide: 2 Na (s) + 2 H 2 O (l) →2 NaOH (aq) + H 2 (g) Metals in the middle of the reactivity series, such as iron , will react with acids such as sulfuric acid (but not water at normal temperatures) to give hydrogen and a metal salt ...

  7. Vanadyl acetylacetonate - Wikipedia

    en.wikipedia.org/wiki/Vanadyl_acetylacetonate

    The complex is generally prepared from vanadium(IV), e.g. vanadyl sulfate: [1] VOSO 4 + 2 Hacac → VO(acac) 2 + H 2 SO 4. It can also be prepared by a redox reaction starting with vanadium pentoxide. In this reaction, some acetylacetone is oxidized to 2,3,4-Pentanetrione. [1]

  8. Contact process - Wikipedia

    en.wikipedia.org/wiki/Contact_process

    The contact process is a method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum was originally used as the catalyst for this reaction; however, because it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium(V) oxide (V 2 O 5) has since been preferred.

  9. Vanadium oxytrichloride - Wikipedia

    en.wikipedia.org/wiki/Vanadium_oxytrichloride

    VOCl 3 is a vanadium compound with vanadium in the +5 oxidation state and as such is diamagnetic. It is tetrahedral with O-V-Cl bond angles of 111° and Cl-V-Cl bond angles of 108°. The V-O and V-Cl bond lengths are 157 and 214 pm, respectively. VOCl 3 is highly reactive toward water and evolves HCl upon standing.
