Answer:

#"H"_3"CCO"_2"H(aq)" + "H"_2"O(l)" rightleftharpoons"H"_3"CCO"_2^(-) + "H"_3"O"^+#

Explanation:

Is charge balanced? Is mass balanced? The answer is yes to both questions.

We write #"K"_a=(["H"_3"O"^+][""^(-)"OAc"])/(["HOAc"]), ("HOAc"-="HO(O=)CCH"_3)#, and under standard conditions, #"K"_a=1.74xx10^-5#.

Please check the value.
