Solubility of CaF_(2) in terms of its solubility product is given by :

Answer»

`s=(K_(sp))^((1)/(3))`
`s=((K_(sp))/(2))^((1)/(3))`
`s=((K_(sp))/(4))^((1)/(3))`
`s=((K_(sp))/(2))^((1)/(2))`

Solution :`CaF_(2)hArr underset(s)(Ca^(2+))+underset(2S)(2F^(-))`
`K_(sp)=(s)(2s)^(2)`
`K_(sp)=4S^(3)`
`s=((K_(sp))/(4))^((1)/(3))`
