The dissociation constant of two acids H...

The dissociation constant of two acids `HA_(1)` and `HA_(2)` are `4.5 xx 10^(-4)` and `1.8 xx 10^(-5)` respectively. If both are having equal concentrations the relative strength of acids is

A

`5:2`

B

`2:5`

C

`5:1`

D

`1:5`

Text Solution

Verified by Experts

The correct Answer is:
C
`(alpha_(1))/(alpha_(2))=sqrt((K_(1))/(K_(2)))=sqrt((4.5xx10^(-4))/(1.8xx10^(-5)))=5:1`
