Vedclass · Answer

(D) buffer solution is a mixture of a weak acid and its conjugate base,or a weak base and its conjugate acid. $NaCl + NaOH$ is a mixture of a strong salt and a strong base,which does not form a buffer. $NaOH + NH_4OH$ is a mixture of a strong base and a weak base,which does not form a buffer. $CH_3COONH_4 + HCl$ results in the formation of $CH_3COOH$ (weak acid) and $NH_4Cl$ (salt of weak base and strong acid),which can act as a buffer,but the mixture itself is not a standard buffer system. Since none of the given options represent a standard buffer system,the correct answer is $D$.
