What is the chemical formula of the compound copper(ii) phosphate? use the list of polyatomic ions and the periodic table to you answer

Cu3(PO4)2

Explanation:

Since oxidation of Cu is +2 hence cation is Cu+2

And anion is trivalent polyatomic, phosphate.

By Criss cross method, exchange the valencies of Cation and anion, we get formula for copper phosphate as below

Cu+2, PO4^3-

Cu3(PO4)2

it's all four options.
