Vedclass · Answer

(B) An acidic buffer is a mixture of a weak acid and its salt with a strong base.$CH_3COOH$ is a weak acid and $CH_3COONa$ is its salt with a strong base $(NaOH)$.Therefore,the mixture of $CH_3COOH + CH_3COONa$ acts as an acidic buffer.$NH_4OH + NH_4Cl$ is a basic buffer (weak base + its salt with strong acid).$NaOH + HCl$ is a strong acid-strong base mixture,not a buffer.
