Question

Based on the solubility guidelines predict the outcome of the following reactions. If you think a precipitation reaction will occur, balance the reaction and write the complete and net ionic equations of the reaction. ( you must show states of the reactants and products)

CuCl2 (aq) + NaOH (aq) =

KI (aq) + Pb(NO3)2 (aq) =

Answer 1

###

CuCl2(aq) + 2NaOH(aq) ==> Cu(OH)2(s) + 2NaCl(aq) (Balanced Reaction)

Molecular equation:-
CuCl2(aq) + 2NaOH(aq) ==> Cu(OH)2(s) + 2NaCl(aq)

Total ionic equation:-
Cu2+(aq) + 2Cl-(aq) + 2Na+(aq) + 2OH-(aq) ==> Cu(OH)2(s) + 2Na+(aq) + 2Cl-(aq)

Net Ionic equation:-
Cu2+(aq) + 2OH-(aq)(aq) ==> Cu(OH)2(s)

###

2KI(aq) + Pb(NO3)2(aq) ==> PbI2(s) + 2KNO3(aq) (Balanced Reaction)

Molecular equation:-

2KI(aq) + Pb(NO3)2(aq) ==> PbI2(s) + 2KNO3(aq)

Total ionic equation:-

2K+(aq) + 2I-(aq) + Pb2+(aq) + 2NO3-(aq) ===> PbI2(s) + 2K+(aq) + 2NO3-(aq)

Net ionic equation:-

Pb2+(aq) + 2I-(aq) ==> PbI2(s)
