Net ionic equations
|
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)
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)
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)
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)
