(a) If the molar solubility of Ag2CO3 at 25 oC is 0.000128 mol/L, what is the Ksp at this temperature? Ksp = (b) It is found that 0.0495 g of PbF2 dissolves per 100 mL of aqueous solution at 25 oC. Calculate the solubility-product constant for PbF2. Ksp = (c) The Ksp of ZnSe at 25 oC is 3.60e-26. What is the molar solubility of ZnSe? solubility = mol/L
