A saturated solution of `CaF_(2)` is found to contain `2 xx 10^(-4) M`

1.	A saturated solution of `CaF_(2)` is found to contain `2 xx 10^(-4) M` of `F^(-)` ions. `K_(sp)` of `CaF_(2)` is:A. `8 xx 10^(-12)`B. `4 xx 10^(-12)`C. `2 xx 10^(-12)`D. `10^(-12)`
Answer» Correct Answer - B `CaF_(2) hArr underset(s)Ca^(2+) + underset(2s)2F^(-)` `2s = 2 xx 10^(-4)` `s = 10^(-4)` `K_(sp) = 4s^(3) = 4 xx 10^(-12)`
