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.
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 Magnéli, [2] they are examples of crystallographic shear compounds based on the rutile ...
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

[7] [8] The tetrathiovanadate [VS 4] 3− is analogous to the orthovanadate ion. [ 9 ] At lower pH values, the monomer [HVO 4 ] 2− and dimer [V 2 O 7 ] 4− are formed, with the monomer predominant at vanadium concentration of less than c. 10 −2 M (pV > 2, where pV is equal to the minus value of the logarithm of the total vanadium ...
A hexahydrate exists below 13.6 °C (286.8 K). [5] Two polymorphs of anhydrous VOSO 4 are known. [6] The V=O bond distance is 160 pm, about 50 pm shorter than the V–OH 2 bonds. In solution, the sulfate ion dissociates rapidly. Being widely available, vanadyl sulfate is a common precursor to other vanadyl derivatives, such as vanadyl ...
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.
In chemical nomenclature when vanadate forms part of the name, it indicates that the compound contains an anion with a central vanadium atom, e.g. ammonium hexafluorovanadate is a common name for the compound [NH 4] 3 [VF 6] with the IUPAC name of ammonium hexafluoridovanadate(III).
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.
