Question

Mixture of $CH_3COOH$ and $CH_3COONH_4$ is an example of acidic buffer. Acidic buffer contains equimolar mixture of weak acid and its salt with weak base.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (D)

If both assertion and reason are false

Answer 2

$CH _{3} COOH / CH _{3} COONH _{4}$ is not an example of acidic buffer. Acidic buffer contains equimolar mixture of weak acid and its salt with strong base. e. g. $CH _{2} COOH / CH _{3} COONa$
