Write the total ionic and net ionic equations for each of the following reactions:

A) hydrobromic acid with potassium hydroxide
B) Nitric acid with barium hydroxide

1 answer

molecular equation:
HBr(aq) + KOH(aq) ==> KBr(aq) + H2O(l)

total ionic:
H^+(aq) + Br^-(aq) + K^+(aq) + OH^-(aq) ==> K^+(aq) + Br^-(aq) + H2O(l)

net ionic equation: just cancel the ions common to both sides. What's left is the NET ionic equation.
H+(aq) + OH^-(aq) ==> H2O(l)

The other equation is just another acid/base reaction.
Ba(OH)2(aq) + 2HNO3(aq) ==> Ba(NO3)2(aq) + 2H2O(l)
