When the following is added to `20 ml` of `0.1 M CH_(3)COOH + 20 ml 0.1 M` of `CH_(3)COONa`. The `pH` of the solution does not change

A

10 mL of 0.1 M `CH_(3)COOH`

B

10mL of 0.1 M `CH_(3)COONa`

C

10 mL of water

D

20 mL of 0.2 M `CH_(3)COOH`

Text Solution

Verified by Experts

The correct Answer is:
C
`pH=pka+log""([S])/([A])`
pH of buffer depends upon the ka, [Salt] and [Acid]
