Question

What net ionic equation describes the reaction when these solutions are mixed?

Na3PO4 (aq) + CaCl2(aq) →


2PO43–(aq) + Cl– (aq) → Cl2(PO4)3(s)
2Ca2+(aq) + Na+(aq) → NaCa2(s)
Na+(aq) + Cl– (aq) → NaCl(s)
2PO43–(aq) + 3Ca2+(aq) → Ca3(PO4)2(s)

Answer 1

It's the fourth option because the first three can't be formed

Cheers.

Answer 2

Almost positive it's the D

Answer 3

Calcium Phosphate is insoluble and Sodium Chloride is soluble

Answer 4

So that eliminates all Sodium ions and Chloride ions from both sides

Answer 5

Thanks guys
