Question

For free response questions, be sure to show all work, report your final answer to the correct number of significant figures, and label even thing 1) Predict the products that will be formed and whether a precipitate will form when Calcium Chloride and Sodium Phosphate are mixed. (Be sure to show all work in order to receive full credit, including the balanced molecular. balanced total ionic, and balanced net ionic equations, all physical states for all three of these equations for all reactants and products).

Explanation / Answer

Balanced equation

3 CaCl2 (aq) + 2 Na3PO4 (aq) ==> Ca3(PO4)2 (s) + 6 NaCl (aq)

Ionic equation

3 Ca+2 (aq) + 6 Cl- (aq) + 6 Na+ (aq) + 2 PO4-3 (aq) ==> Ca3(PO4)2 (s) + 6 Na+ (aq) + 6 Cl- (aq)

Net Ionic equation

2 PO4-3 (aq) + 3 Ca2+ (aq) ==> Ca3(PO4)2 (s)
