Q60 / 180 · NEET 2015 (Phase 2) · Chemistry

Which one of the following pairs of solution is not an acidic buffer?

Correct answer
A
$H C l O_{4}$ and $N a C l O_{4}$
B
$C H_{3} C O O H$ and $C H_{3} C O O N a$
C
$H_{2} C O_{3}$ and $N a_{2} C O_{3}$
D
$H_{3} P O_{4}$ and $N a_{3} P O_{4}$

Solution

Strong acid with its salt cannot form buffer solution.

H C l O_{4}

and

N a C l O_{4}

cannot act as an acidic buffer.

Hence, the correct answer is option: 'A'.
