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

A

`1 xx 10^(-3)`

B

`1 xx 10^(-7)`

C

`1 xx 10^(-5) M`

D

`1 xx 10^(-14)`

Text Solution

Verified by Experts

The correct Answer is:
C
`Ka = Calpha^(2)`
`K_(a) = 0.1 xx((1)/(100))^(2)`
`0.1 = (0.01)^(2)`
`=0.00001 = 1 xx 10^(-5)`
