Solid calcium fluoride, CaF2, is added to water at 25°C. When equilibrium is achieved between the undissolved CaF2 and the solution, the calcium ion concentration was found to be 0.00021 M. Assuming that CaF2 dissociates completely in water and there are no other important equilibria involving Ca2+ or F ? ions in the solution, calculate Ksp for calcium fluoride.
