Find the relative strength of two weak acids HA `(K_(a)=8.0xx10^(-5))` and `HB (K_(b) = 2.0xx10^(-5))`.

Text Solution

Verified by Experts

The correct Answer is:
2
Relative strength of two weak acids `=(sqrt(K_(a_(1)).c))/(sqrt(K_(a_(2)).c))`
If `c_(1)=c_(2)`
`R.S. = sqrt((K_(a_(1)))/(K_(a_(2))))=sqrt((8.0xx10^(-5))/(2.0xx10^(10^(-5))))=2`
