A weak base MOH of `0.1` N concentration shows a pH value of 9. What is the precentage degree of dissociation of the base?

A

`0.01%`

B

`0.001%`

C

`0.1%`

D

`0.02%`

Text Solution

Verified by Experts

The correct Answer is:
3
`pH=9,[OH^(-)]=10^(-5),Calpha=10^(-5):.alpha=10^(-4)`
`%` ionization `10^(-4)xx100=0.01%`
