What is the pH at the equivalenve point for the titration of `0.20 M` aniline `(K_(b) = 7.95 xx 10^(-10))` with `0.20 M HCL`

A

`2.8`

B

`11.1`

C

`5.2`

D

`9.42`

Text Solution

Verified by Experts

The correct Answer is:
A
At the equivalence point in the titration of weak base and strong acid, it is the salt that is formed which undergoes hydrolysis
`:. pH = 7 - (1)/(2) pK_(b) - 1/2 "log"C`
