Question- 1) Calculate the solubility of-
a. PbF2 for which the Ksp = 3.3 x 10-8
b. What is the solubility of PbF2 in 0.025 M NaF solution?
2. In a saturated CaF2 solution at 25oC, the calcium concentration is analyzed to be 9.1 mg/L. Use this value to calculate the Ksp of CaF2 assuming that the solute dissociated completely into Ca2+ and F- ions and that neither ion reacts with water. Remember, for equilibrium constants, the concentrations must be in mol/L or molar concentrations.
Rework your solution from the beginning and check each step carefully.
