Write the net ionic reaction from the following balanced reactions:
1. FeCl3 (aq) + K3PO4 (aq) = FePO4 (s) + 3 KCI (aq)
2. Ba(NO3)2 (aq) + Ag2SO4 (aq) = 2 AgNO3(aq) + BaSO4 (s)
3. (NH4)2CO3 (aq) + Ca(NO3)2 (aq) = 2 NH4NO3 (aq) + CaCO3 (s)
4. 2 K3PO4 (aq) + 3 Ni(NO3)2 (aq) = Ni3(PO4)2 (s) + 6 KNO3 (aq)
5. 2 LiOH (aq) + Cu(C2H3O2)2 (aq) = Cu(OH)2 (s) + 2 Li C2H3O2 (aq)
The excess I2(aq) left over from the above reaction was titrated with 11.37 mL of 0.0105 M thiosulfate (S2O32-) as follows: I2(aq) + 2S2O32-(aq) → 2I1-(aq) + S4O62-(aq)
