A buffer solution of `pH =9` can be prepared by mixing

A

`CH_(3)COONa` and `CH_(3)COOHs`

B

NaCl and NaOH

C

`NH_(4)Cl` and `NH_(4)OH`

D

`KH_(2)PO_(4)` and `K_(2)HPO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
A basic buffer `(pH=9)` is formed by mixing a solution of a weak base and its salt with a strong acid. Therefore, correct choice is (C ) i.e., `NH_(4)OH` and `NH_(4)Cl`
