Hexamolybdate

Hexamolybdate is a series of inorganic compounds with the formula A6[Mo7O24] 14H2O, where A is a monovalent cation such as sodium, potassium, or ammonium. These compounds are composed of a central molybdenum heptoxide core (Mo7O24) surrounded by six monovalent cations and 14 water molecules.

Hexamolybdates are typically synthesized by reacting a solution of a monovalent metal carbonate with a solution of ammonium heptamolybdate. The resulting compound is usually a blue or purple powder that is highly soluble in water. Hexamolybdates are used in various industrial applications, including the production of pigments, catalysts, and biocides.

The properties of hexamolybdates are influenced by the type of monovalent cation used in their synthesis. For example, potassium hexamolybdate is highly soluble and has been used as a pigment in paints and coatings, while sodium hexamolybdate is less soluble and has been used as a biocide in the treatment of wastewater.

In terms of their chemical behavior, hexamolybdates are known to be highly reactive and can undergo a variety of chemical reactions, including oxidation and reduction. They are also capable of forming complexes with other metal ions, which can lead to the formation of new compounds with unique properties.

Overall, hexamolybdates are a class of compounds with a range of industrial applications and interesting chemical properties. Further research is needed to fully understand the behavior and potential uses of these compounds.
