Question

Enter the net ionic equation, including phases, for the reaction of AgNO3(aq) with Ba(OH)2(aq).

Answer 1

First write out the balanced equation (use solubility rules to help you predict phases):
2AgNO3 (aq) + Ba(OH)2 (aq) --> 2AgOH (s) + Ba(NO3)2 (aq)
now write all (aq) as ions as they are deionzed in solution:
2Ag+ (aq) + 2NO3- (aq) + Ba2+ (aq) + 2OH- (aq) --> 2AgOH (s) + Ba2+ (aq) + 2NO3- (aq)
finally crossout spectator ions (ions that appear on both sides):
2Ag+ (aq) + 2OH- (aq) --> 2AgOH (s)
