Ionisation constant of HA (weak acid) an...

Ionisation constant of HA (weak acid) and BOH (weak base) are `3.0xx10^(-7)` each at 298 K. the percentage extent of hydrolysis of BA at the dilution of 10 L is :

A

25

B

50

C

75

D

40

Text Solution

Verified by Experts

The correct Answer is:
A
`h/(1-h)=sqrtK_h=sqrt(K_omega/(K_aK_b))=sqrt((10^(-14))/((3xx10^(-7))^2)=1/3implies h=0.25`
