At `25^(@)C`, the ionic mobility of `CH_(3)COO^(-)`, `H^(+)` are respectively `4.1xx10^(-4),3.63xx10^(-3)`cm/sec. The conductivity of `0.01"M CH"_(3)COOH` is `5xx10^(-5)" S.cm"^(-1)`. Dissociation constant of `CH_(3)COOH` is

A

`1.34 xx 10^(-4)`

B

`3 xx 10^(-4)`

C

`3 xx 10^(-5)`

D

`3 xx 10^(-6)`

Text Solution

Verified by Experts

The correct Answer is:
A
`K_(alpha) = Calpha^(2) , `
`alpha = lambda_(c)/lambda_(infty) , lambda_(infty) = F(mu_(c)^(0) + mu_(a)^(0))`
