Question

What is the net ionic equation for the reaction that is represented by the following total ionic equation?

6 upper N a superscript plus, plus 2 upper P upper O subscript 4 superscript 3 minus, plus 3 upper C a superscript 2 plus, plus 6 upper C l superscript minus right arrow 6 upper N a superscript plus, plus 6 upper C l superscript minus, plus upper C a subscript 3 (upper O upper O subscript 4) subscript 2.
2 upper N a subscript 3 upper P upper O subscript 4 plus 3 upper C a upper C l subscript 2 right arrow 6 upper N a upper C l plus upper C a subscript 3 (upper P upper O subscript 4) subscript 2.
2 upper P upper O subscript 4 superscript 3 minus, plus 3 upper C a superscript 2 plus right arrow upper C a subscript 3 (upper P upper O subscript 4) subscript 2.
2 upper P upper O subscript 4 superscript 3 minus, plus 3 upper C a superscript 2 plus, plus 6 upper C l superscript minus right arrow 6 upper N a superscript plus, upper C a subscript 3 (upper P upper O subscript 4) subscript 2.
2 upper P superscript 5 plus, plus 8 upper O superscript 2 minus, plus 3 upper C a superscript 2 plus right arrow upper C a subscript 3 (upper P upper O subscript 4) subscript 2.

Answer 1

2 PO4^3-(aq) + 3 Ca^2+(aq) → Ca3(PO4)2(s)
