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 ...
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.
Organovanadium compounds find only minor use as reagents in organic synthesis but are significant for polymer chemistry as catalysts. [17] Vanadocene dichloride is a versatile starting reagent and has applications in organic chemistry. [18] Vanadium carbonyl, V(CO) 6, is a rare example of a paramagnetic metal carbonyl. Reduction yields V (CO) −
333t an undergraduate chemistry student could understand, and a high school student could get the gist of. Make the section briefer; currently this section is about as long as the "uses" section. Considering the huge importance of the uses of V2O5, that makes it unbalanced.
Ammonium metavanadate is the inorganic compound with the formula NH 4 VO 3. It is a white salt, although samples are often yellow owing to impurities of V 2 O 5. It is an important intermediate in the purification of vanadium. [2]
In chemistry, a vanadate is an anionic coordination complex of vanadium. Often vanadate refers to oxoanions of vanadium , most of which exist in its highest oxidation state of +5. The complexes [V(CN) 6 ] 3− and [V 2 Cl 9 ] 3− are referred to as hexacyanovanadate(III) and nonachlorodivanadate(III), respectively.
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.
