Question

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

Answer 1

Cu and atomic number 29. copper is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.

Answer 2

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
