3M solution of Na2CO3 is boiled in a closed container with excess of CaF2. Very little amount of CaCO3 and NaF are formed. If the solubility product Ksp of CaCO3 is y and molar solubility of CaF2 in water is x, find the molar concentration of F− in resulting solution after equilibrium is attained.

3M solution of Na2CO3 is boiled in a closed container with excess of C

1.	3M solution of Na2CO3 is boiled in a closed container with excess of CaF2. Very little amount of CaCO3 and NaF are formed. If the solubility product Ksp of CaCO3 is y and molar solubility of CaF2 in water is x, find the molar concentration of F− in resulting solution after equilibrium is attained.
Answer» $3 M$ solution of $N a_{2} C O_{3}$ is boiled in a closed container with excess of $C a F_{2} .$ Very little amount of $C a C O_{3}$ and $N a F$ are formed. If the solubility product $K_{s p}$ of $C a C O_{3}$ is y and molar solubility of $C a F_{2}$ in water is x, find the molar concentration of $F^{-}$ in resulting solution after equilibrium is attained.
