    For each of the following sets of reactants,

    1. Write the balanced molecular equation:

    2. Write the ionic equation:

    3. List the spectator ions:

    4. Write the net ionic equation:

    Set 1: Al(NO3)3(aq) + 3 NaOH (aq) -------> Al(OH)3 (s) + 3 NaNO3 (aq)

    ionic eqn:

    Al+3 (aq) + 3 NO3- (aq) + 3 Na+(aq) + 3 OH- (aq) -------> Al(OH)3 (s) + 3 Na+ (aq) + 3 NO3-(aq)

    net ionic eqn:

    Al+3 (aq) + 3 OH- (aq) -------> Al(OH)3 (s)

    spectator ions:

    3 Na+ (aq) , 3 NO3- (aq)



    Set 2: 2 Li3PO4(aq) + 3 Sr(OH)2 (aq) -------> 6 LiOH (aq) + Sr3(PO4)2 (s)

    ionic eqn:

    6 Li+ (aq) + 2 PO43- (aq) + 3 Sr+2 (aq) + 6 OH- (aq) -------> 6 Li+ (aq) + 6 OH- (aq) + Sr3(PO4)2 (s)

    net ionic eqn:

    3 Sr+2 (aq) + 2 PO43- (aq) -------> Sr3(PO4)2 (s)

    spectator ions:

    6 Li+ (aq) , 6 OH- (aq)



    Set 3: 2 CuClO4 (aq) + Sr(OH)2 (aq) -------> 2 CuOH (s) + Sr(ClO4)2 (aq)

    ionic eqn:

    2 Cu+ (aq) + 2 ClO4- (aq) + Sr+2 (aq) + 2 OH- (aq)-------> 2 CuOH (s) + Sr+2 (aq)+ 2 ClO4- (aq)

    net ionic eqn:

    2 Cu+ (aq) + 2 OH- (aq) -------> 2 CuOH (s)

    spectator ions:

    Sr+2 (aq) , 2 ClO4- (aq)



    Set 4: Na2CO3 (aq) + FeSO4 (aq) -------> Na2SO4 (aq) + FeCO3 (s)

    ionic eqn:

    2 Na+ (aq) + CO32- (aq) + Fe+2 (aq) + SO42- (aq) -------> 2 Na+ (aq) + SO42- (aq) + FeCO3 (s)

    net ionic eqn:

    Fe+2 (aq) + CO32- (aq) -------> FeCO3 (s)

    spectator ions:

    2 Na+ (aq) , SO42- (aq)
