$0.05 \ M \ KClO_4 + 0.5 \ M \ HClO_4$

Vedclass · Answer

(D) buffer solution is formed by a weak acid and its conjugate base,or a weak base and its conjugate acid. $H_2S$ is a weak acid and $KHS$ is its conjugate base,so option $A$ is a buffer. $C_6H_5NH_2$ (aniline) is a weak base and $C_6H_5NH_3Br$ is its conjugate acid,so option $B$ is a buffer. $H_2CO_3$ is a weak acid and $KHCO_3$ is its conjugate base,so option $C$ is a buffer. $HClO_4$ is a strong acid. $A$ mixture of a strong acid and its salt does not form a buffer solution. Therefore,option $D$ is not a buffer.
