$HClO_4 + NaClO_4$

Vedclass · Answer

(A) An acidic buffer is a mixture of a weak acid and its salt with a strong base.$CH_3COOH + CH_3COONa$ is a mixture of a weak acid and its salt.$HCN + NaCN$ is a mixture of a weak acid and its salt.$H_3BO_3 + Na_2B_4O_7$ acts as a buffer system.$HClO_4$ is a strong acid and $NaClO_4$ is its salt with a strong base $(NaOH)$. $A$ mixture of a strong acid and its salt does not form a buffer solution. Therefore,$HClO_4 + NaClO_4$ is not an acidic buffer.
