CH_{3}COOH is a weak acid because CH_{3}COOH gets partially dissociated into ions in aqueous solution and HCl completely dissociates into ions in solution.

Eg.- Add zinc metal in CH_{3}COOH and HCl respectively. The Hydrogen gas evolved slowly in CH_{3}COOH and faster in HCl. It shows acetic acid (CH_{3}COOH) is a weak acid.
