A weak acid HX has the dissociation constant `1xx 10 ^(-5) ` M.It forms a salt NaX on reactions with alkali. The percentage hydrolysis of 0.1 M solution of NaX is :

A

`0.0001 %`

B

`0.01 %`

C

` 0.1 %`

D

` 0.15%`

Text Solution

Verified by Experts

The correct Answer is:
B
` h= sqrt ((K_h)/( C) ) =sqrt((K_w)/( K_a.C) ) =sqrt( 10 ^(_4)/( 10^(-5)xx 10^(-1) ) ), h = 10 ^(_4) `
` % h= 0.01 %`
