Calcium phosphates are historically known as good material for tooth replacement, repair of large bone defects caused by tumors and as injectable cement. One simple way of producing calcium phosphate is by collecting it from the reaction of Calcium chloride and Sodium phosphate. What is the balanced chemical equation for the production of calcium phosphate?
CaCl2 + Na3PO4 → Ca3(PO4)2 + NaCl
2CaCl2 + Na3PO4 → Ca2PO4 + 3NaCl
3CaCl2 + 2Na3PO4 → Ca3(PO4)2 + 6NaCl
3CaCl2 + Na3PO4 → Ca3(PO4)2 + 3NaCl
