What is the solubitity equillibrium equation for CaF2 (a sparingly soluble salt)

Question

What is the solubitity equillibrium equation for CaF2 (a sparingly soluble salt)? What is the ecpression for CaF2? For the next three (3) questions, the Ksp of Ag2CO3 is determined by precipitation, equilibration of the precipitate with the solution, and then determination of [CO32-] in the solution. The resulting solution was found to have [CO32-] = 1.3 Times 10-4. What is the solubility equilibrium equation for Ag2CO3 (a sparingly soluble salt)? What is the value for [Agr] in the solution? 3.3 Times 10 s 2.6 Times 10-4 6.5 Times 105 5.2 Times 10-4 1.3 Times 10-4
