Vanadium(II) sulfate describes a family of inorganic compounds with the formula VSO 4 (H 2 O) x where 0 ≤ x ≤ 7. The hexahydrate is most commonly encountered. It is a violet solid that dissolves in water to give air-sensitive solutions of the aquo complex. The salt is isomorphous with [Mg(H 2 O) 6]SO 4.

Vanadium(III) sulfate is the inorganic compound with the formula V 2 (SO 4) 3. It is a pale yellow solid that is stable to air, in contrast to most vanadium(III) compounds. It slowly dissolves in water to give the green aquo complex [V(H 2 O) 6] 3+. The compound is prepared by treating V 2 O 5 in sulfuric acid with elemental sulfur: [2]
Vanadyl(IV) sulfate describes a collection of inorganic compounds of vanadium with the formula, VOSO 4 (H 2 O) x where 0 ≤ x ≤ 6. The pentahydrate is common. The pentahydrate is common. This hygroscopic blue solid is one of the most common sources of vanadium in the laboratory, reflecting its high stability.
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]
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. [2] 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 oxidation ...

Pronunciation is the way in which a word or a language is spoken. This may refer to generally agreed-upon sequences of sounds used in speaking a given word or language in a specific dialect ("correct" or "standard" pronunciation) or simply the way a particular individual speaks a word or language.
