A
$H_2CO_3$ and $Na_2CO_3$
B
$H_3PO_4$ and $Na_3PO_4$
C
$HClO_4$ and $NaClO_4$
D
$CH_3COOH$ and $CH_3COONa$
Detailed Solution
An acidic buffer is a weak acid with its salt.
$HClO_4$ is a strong acid, so $HClO_4$ and $NaClO_4$ cannot act as an acidic buffer.
$HClO_4$ is a strong acid, so $HClO_4$ and $NaClO_4$ cannot act as an acidic buffer.
