The `pH` of an aqueous solution of `0.1 M` solution of a weak monoprotic acid which is `1%` ionised is

A

`1`

B

`2`

C

`3`

D

`11`

Text Solution

Verified by Experts

The correct Answer is:
C
`underset(0.1(1-(1)/(100)))underset(0.1)(HA)hArrunderset((1xx0.1)/(100))underset()(H^(+))+underset((1xx0.1)/(100))underset()(A^(-))`
`[H^(+)]=10^(-3)`
` :. pH=3`
