All of the following acids dissociate completely in water, except

• A. HCl
• B. $H_{2}S{O}_4$
• C. $C{H}_{3}COOH$
• D. $HN{O}_3$

Answer 1

The correct option is C $C{H}_{3}COOH$

Acetic acid $\left(C{H}_{3}COOH\right)$ is a weak acid and does not dissociate completely in water.

Hence, the correct answer is option (C).
