What is formula for copper ii phosphate?

Copper II phosphate is an inorganic compound with the chemical formula Cu3(PO4)2. Its molecular weight is 380.58 g/mol. It is a blue-green solid with low solubility in water. Its crystal structure is orthorhombic. Copper II phosphate is mainly used in the manufacture of ceramics and as a pigment in paints. Its synthesis involves reacting copper II sulfate and sodium phosphate in water, followed by precipitation and purification steps. The balanced chemical equation for the synthesis of copper II phosphate is:

3 CuSO4(aq) + 2 Na3PO4(aq) → Cu3(PO4)2(s) + 3 Na2SO4(aq)

where CuSO4 is copper II sulfate, Na3PO4 is sodium phosphate, and Na2SO4 is sodium sulfate.
