    \[Ba(OH)_{2}(aq)+2CH _{3}OOH(aq) \rightarrow 2H _{2}O(l)+Ba(CH _{3}OO)_{2}(aq)\]

    that is the balanced equation

    \[Ba ^{2+}(aq)+2OH ^{-}(aq)+2H ^{+}(aq)+2CH _{3}OO ^{-}(aq)\rightarrow2H _{2}O(l)+Ba(CH _{3}OO)_{2}(aq)\]

    chould be the balanced ionic equation

    Getting rid of the spectator ions should leave 2H and 2OH

    \[H ^{+}(aq)+OH ^{-}(aq)\rightarrow H _{2}O(l)\]

    but I am told by mastering chemistry, "This is not the expected net ionic reaction when the reaction involves a weak acid such as acetic acid."

    So I tried \[CH _{3}OOH(aq)+OH ^{-}(aq)\rightarrow H _{2}O(l)+CH _{3}OO ^{-}(aq)\]

    Still wrongaccording to mastering chemistry

    I believe it is: \[CH_3OOH(aq) + H_2O (l) \rightarrow H_3O^+ (aq)+ CH_3OO^- (aq)\]
