Question

Write the net ionic equation for this reaction occurring in water: Sodium phosphate and calcium chloride are mixed to form sodium chloride and calcium phosphate.
1. No reaction occurs.
2. 2Na3PO4 + 3Ca2+ -> 6Na+ + Ca3(PO4)2
3. 2 PO3−4 + 3Ca2+ -> Ca3(PO4)2
4. PO2−4 + Ca2+ -> CaPO4
5. 2 PO3−4 + 3CaCl2 -> 6Cl− + Ca3(PO4)2

Answer 1

Answer:

When Calcium chloride react with sodium phosphate it forms solid calcium phosphate and sodium chloride as follow:

3CaCl2 + 2Na3PO4 = Ca3(PO4)2 + 6NaCl.

3Ca+2 + 6Cl- + 6Na+ 2PO4(-3) = 3Ca+2 + 2PO4(-3) 6Na+ 6Cl-
