Assertion: Mixture of CH3COOH\mathrm{CH}_3 \mathrm{COOH} and CH3COONH4\mathrm{CH}_3 \mathrm{COONH}_4 is an example of acidic buffer. Reason: Acidic buffer contains equimolar mixture of weak acid and its salt with weak base.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

CH3COOH/CH3COONH4\mathrm{CH}_3 \mathrm{COOH} / \mathrm{CH}_3 \mathrm{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. CH3COOH/CH3COONa\mathrm{CH}_3 \mathrm{COOH} / \mathrm{CH}_3 \mathrm{COONa}.
