At `25^(@)C` the solublility product of `Hg_(2)CI_(2)` in water is `3.2 xx 10^(-17) mol^(3) dm^(-9)`. What is the solubility of `Hg_(2)CI_(2)` in water at `25^(@)C`?

A

`1.2xx10^(-12)` M

B

`3.0xx10^(-6)` M

C

`2xx10^(-6)` M

D

`1.2xx10^(-16)` M

Text Solution

Verified by Experts

The correct Answer is:
C
`Hg_(2)CIhArrHg_(2)^(+2)+2CI^(-)`
`Ksp=[Hg_(2)^(+2)][CI^(-)]^(2)=4S^(3)`
`4S^(3)=32xx10^(-18)`
`S^(2)=8xx10^(-18)`
`S=2xx10^(-6)mol//L`
