Solubility of `BaF_(2)` in a solution of `Ba(NO_(3))_(2)`, will be represented by the concentration term:A. `[Ba^(2+)]`B. `[F^(-)]`C. `1//2[F^(-)]`D. `2[NO_(3)^(+)]`

Answer» Correct Answer - C
Let `S` is the solubility of `BaF_(2)` in a solution of `BaNO_(3)`
Then `K_(SP)=[Ba^(2+)][F^(-)]^(2)`
Then `[F^(-)]=2S`,
Then `(1)/(2)[F^(-)]=S`
