If both the Assertion and Reason are incorrect.

(D) An acidic buffer is a solution containing a mixture of a weak acid and its salt with a strong base.$CH_3COOH$ is a weak acid,but $CH_3COONH_4$ is a salt of a weak acid $(CH_3COOH)$ and a weak base $(NH_4OH)$.Therefore,the mixture of $CH_3COOH$ and $CH_3COONH_4$ does not form an acidic buffer.Since the assertion is false and the definition provided in the reason is also incorrect (it should be a salt with a strong base),both the assertion and the reason are incorrect.

$20$ mL of a solution of acetic acid required $28.4$ mL of $0.1$ $M$ NaOH for its neutralization. $A$ solution $(X)$ was prepared by mixing $20$ mL of the above acetic acid and $14.2$ mL of $0.1$ $M$ NaOH solution. What is the pH of the solution $(X)$? ($pK_a$ value of acetic acid is $4.75$).

The $pH$ of a sodium acetate buffer solution is given by the Henderson-Hasselbalch equation: $pH = pK_a + \log \frac{[Salt]}{[Acid]}$. For acetic acid,if $[Salt] = [Acid] = 0.1 \ M$,then the $pH$ of the solution is: $[K_a = 1.8 \times 10^{-5}]$
