Answer

Explanation:

Step1: Determine ion charges

Copper(II) has a +2 charge ($Cu^{2 + }$), and the phosphate ion has a - 3 charge ($PO_{4}^{3 - }$).

Step2: Balance charges

To balance the charges, we need 3 copper(II) ions to give a total of +6 charge and 2 phosphate ions to give a total of - 6 charge.

Answer:

$Cu_{3}(PO_{4})_{2}$
