Use balanced equations to determine whether either CuBr or Ca3(PO4)2 has a different solubility with a change in pH:
a) CuBr changes solubility with changing pH. Ca3(PO4)2 does not change solubility.
b) Neither CuBr nor Ca3(PO4)2 change solubility with changing pH. Ca3(PO4)2 changes solubility with changing pH.
c) CuBr does not change solubility.
d) Both CuBr and Ca3(PO4)2 change solubility with changing pH.
