In `0.1 M`- solution, a mono basic acid is `1%` ionized. The ionisation constant of the acid is `

A

`1xx10^(-3)`

B

1xx10^(-7)`

C

`1xx10^(-5)`

D

`1xx10^(-14)`

Text Solution

Verified by Experts

The correct Answer is:
C
`Ka=Calpha^(2)`
`K_(a)=0.1xx((1)/(100))^(2)=0.1xx(0.01)^(2)`
`=0.00001=1xx10^(-5)`
