The percentage degree of hydrolysis of a salt of weak acid (HA) and weak base (BOH) in its 0.1 M solutions is found to be 10% If the molarity of the solution is 0.05M , the percentage hydrolysis of the salt should be :

A

`5% `

B

` 10 %`

C

` 20%`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
The formula is h = `(h)/(1-h) =sqrt((K_w)/( K_a. K_b))`
In this formula , Conc. Term is absent i.e., .h. does not depend on concentration .
