Question

Which equation best represents the net ionic equation for the reaction that occurs when aqueous solutions of

potassium phosphate and iron(II) nitrate are mixed?

3Fe2+ (aq) + 2PO4³-(aq) → Fe3(PO4)2(s)

2K+ (aq) + Fe(NO3)2(aq) → 2KNO3(aq) + Fe²+ (aq)

3Fe2+ (aq) + 2PO4³ (aq) → Fe3(PO4)2(aq)

2K3PO4(aq) + 3Fe2+ (aq) → Fe3(PO4)2(s) + (K+)6(aq)

2K3PO4(aq) + 3Fe(NO3)2(aq) → Fe3(PO4)2(s) + 6KNO3(aq)

Answer 1

The net ionic equation for the reaction that occurs when aqueous solutions of potassium phosphate and iron(II) nitrate are mixed is:

3Fe2+(aq) + 2PO43-(aq) → Fe3(PO4)2(s)

Therefore, the correct answer is A.
