If for a binary weak electrolyte the solubility product is `4xx10^(-10) ` at 298K.Calculate its solubility is mol `dm^(-3)` at the same temperature

A

`4 xx 10^(-5)`

B

` 2 xx 10^(-5)`

C

` 8 xx 10^(-10)`

D

`16 xx 10^(-20)`

Verified by Experts

The correct Answer is:

B

`AB hArrA^(+)+B^(-),K_(sp)=S^(2)`
`S=sqrt(K_(sp))=sqrt(4xx10^(10))=2xx10^(-5)`
