Given the reaction and the solubility informa-
tion below, write the net ionic equation for
the reaction potassium phosphate(aq) + lead(II) nitrate(aq)

General solubility guidelines:

1) Most sodium, potassium and ammonium compounds are soluble in water.
2) Most nitrates, acetates and chlorates are
soluble.
3) Most chlorides are soluble, except those for silver, mercury(I) and lead. Lead(II) chloride is soluble in hot water.
4) Most sulfates are soluble, except those of barium, strontium and lead.
5) Most carbonates, phosphates and silicates are insoluble, except those of sodium,
potassium and ammonium.
6) Most sulfides are insoluble, except those of calcium, strontium, sodium, potassium
and ammonium.

1. 3 Pb2+(aq) + 2 PO3-4 (aq) ----> Pb3(PO4)2(s)

2. 2K3PO4(aq) + 3 Pb(NO3)2(aq) -> 6KNO3(aq) + Pb3(PO4)2(s)

3. 6K+(aq) + 2 PO3-4 (aq)+3 Pb2+(aq) + 6NO-3 (aq) -> 6K+(aq) + 6NO-3 (aq) + Pb3(PO4)2(s)

4. 2K3PO4(aq) + 3 Pb(NO3)2(aq) -> 6K+(aq) + 6NO-3 (aq) + Pb3(PO4)2(s)

5. None of these
