Final answer:
When aqueous acetic acid is neutralized by aqueous barium hydroxide, the reaction results in the formation of water and a salt.
Step-by-step explanation:
When aqueous acetic acid is neutralized by aqueous barium hydroxide, the reaction results in the formation of water and a salt. This is represented by the balanced chemical equation: CH3COOH(aq) + Ba(OH)2(aq) → H2O(l) + Ba(CH3COO)2(aq). The process of neutralization involves the combination of an acid and a base to produce water and a salt.
