The degree of dissociation of an acid HA...

The degree of dissociation of an acid HA in 0.1 M solution is 0.1%. Its dissociation constant is

A

`1 xx 10^(-3)`

B

`1 xx 10^(-7)`

C

`1 xx 10^(-10)`

D

`1 xx 10^(-14)`

Text Solution

Verified by Experts

The correct Answer is:
B
`alpha = 0.1% = 0.001`
c= 0.1M
`:.` Dissociation constant, `K = alpha^(2)c = (0.001)^(2) xx 0.1 = 10^(-7)`
