(a) If the molar solubility of BaCO3 at 25 oC is 5.08e-05 mol/L, what is the Ksp at this temperature? Ksp = (b) It is found that 5.73e-05 g of Zn3(AsO4)2 dissolves per 100 mL of aqueous solution at 25 oC. Calculate the solubility-product constant for Zn3(AsO4)2. Ksp = (c) The Ksp of Ag2CO3 at 25 oC is 8.46e-12. What is the molar solubility of Ag2CO3? solubility = mol/L
