VOSO4H2O

VOSO4H2O is a chemical compound with the formula VOSO4H2O, also known as ammonium metavanadate. It is a hydrate of the metavanadate ion, [VO3]2-, with an ammonium ion, NH4+, replacing one of the hydrogen atoms in the water molecule.

The compound is a pale yellow to white solid that is highly soluble in water. It is used as a precursor to other vanadium compounds, as well as a source of vanadium in various industrial and chemical applications. VOSO4H2O is also used as a catalyst in certain chemical reactions and as an additive in some catalysts.

The structure of VOSO4H2O consists of a metavanadate ion, in which a vanadium atom is bonded to three oxygen atoms and one sulfate ion, SO42-. The ammonium ion is bonded to the sulfate ion through hydrogen bonding. This lattice structure gives the compound its high solubility in water.

VOSO4H2O is typically synthesized through the reaction of vanadium oxide with sulfuric acid and ammonium hydroxide. The product is then isolated and purified through recrystallization. It is an important intermediate in the production of other vanadium compounds, including vanadium pentoxide, which is used in the production of catalysts, batteries, and other applications.

Overall, VOSO4H2O is a versatile and useful chemical compound with a wide range of applications. Its high solubility and ability to act as a catalyst make it an important intermediate in many industrial processes.
