Which of the following solutions cannot act as a bufler?

A

`NaH_(2)PO_(4) + H_(3)PO_(4)`

B

`CH_(3)COOH+CH_(3)COON`

C

`HCI+ NH_(4)CI`

D

`H_(3)PO_(4)+NaHPO_(4)`

Text Solution

Verified by Experts

The correct Answer is:

C

Weak acid + Salt of weak acid rarr Buffer solution
(OR)Weak base + Salt of weak base rarr Buffer solution
Since, `HCI +NH_(4)Cl` mixture contains strong acid (HCI), it cannot act as a buffer.
