Question

Which of the following compounds is a weak acid?

• A. HCl
• B. \( CH_3COOH \)
• C. \( H_2SO_4 \)
• D. \( HNO_3 \)

Hint:

Strong acids completely ionize in water, whereas weak acids only partially ionize.

Answer 1

The Correct Option is B

A weak acid only partially ionizes in water. Acetic acid (\( CH_3COOH \)) is a weak acid because it does not completely dissociate in solution, unlike strong acids such as \( HCl, H_2SO_4, \) and \( HNO_3 \). Thus, the correct answer is \( \mathbf{(B) CH_3COOH} \).
