Question

Enter question here...Why does the addition of acid increase the solubility of calcium phosphate? Why does the addition of acid increase the solubility of calcium phosphate? It decreases the phosphate ion concentration, forcing the equilibrium to the right. It increases the phosphate ion concentration, forcing the equilibrium to the right. It decreases the phosphate ion concentration, forcing the equilibrium to the left. It increases the phosphate ion concentration, forcing equilibrium to the left. It decreases the calcium ion concentration, forcing the equilibrium to the right. It increases the calcium ion concentration, forcing the equilibrium to the right. It decreases the calcium ion concentration, forcing the equilibrium to the left. It increases the calcium ion concentration, forcing equilibrium to the left.

Explanation / Answer

It decreases the phosphate ion concentration, forcing the equilibrium to the right---if the reaction is written as:
Ca3(PO4)2 <==> 3Ca(2+) + 2PO4(3-)
