A buffer solution is prepared by mixing equal concentration of acid (ionisation constant `K_(a)`) and a salt. The pH of buffer is

A

`pK_(a)+7`

B

`14-pK_(a)`

C

`pK_(a)`

D

`pK_(a)+1`

Verified by Experts

The correct Answer is:

C

pH of buffer is
`pH =pK_(a)+log. (["salt"])/(["acid"])`
Since , [salt] =[acid] , `pH = pK_(a)`
