Calculate the hydrolysis constant of a salt of week acid `(K_(a) = 2 xx 10^(-6))` and of a weak base `(K_(b) = 5 xx 10^(-7))`

A

`10^(-4)`

B

`10^(-2)`

C

`10^(-6)`

D

`10^(-8)`

Text Solution

Verified by Experts

The correct Answer is:
B
`K_(h) = (kw)/(k_(a).k_(b)) = (10^(-14))/(2 xx 10^(-6) xx 5 xx 10^(-7))`
