A buffer solution contains 0.1 M each of acetic acid and sodium acetate. The pH of the buffer solution is `(pK_(a)(CH_(3)COOH)=4.75)` :

A

`4.75`

B

`5.75`

C

`6.75`

D

`9.25`

Text Solution

Verified by Experts

The correct Answer is:
A
`pH=pK_(a)+"log"(["Salt"])/(["Acid"])`
`=4.75+log 1=4.75`
