In a saturated solution of an ionic compound in water there is an equilibrium between the solid compound and the dissolved ions. The equilibrium expression for this type of reaction is called the solubility product constant, K_sp, which can be calculated from the concentrations in moles per liter, of each ion in solution. For example, the solubility reaction and solubility product of carbonate, are BaCO_3(s) Ba^2+(aq) + CO_3^2-(aq) K_sp = [Ba^3-] [CO_3^2-] Similarly, the solubility reaction and solubility product of calcium sulfate, CaSO_4, are CaSO_4(s) Ca^2+ (aq) + SO^3- (aq) K_sp = [Ca^2+] [SO_4^2-] The solubility of barium carbonate, BaCO_3, is 0.0100 g/L, its molar mass is 197.3 g/mol. What is the K_sp of barium carbonate? Express your answer numerically. The solubility product constant of calcium sulfate. CaSO_4 is 7.10 times 10^-3. Its molar mass is 136.5 g/mol. How many grams of calcium sulfate can dissolve in 83.0 L of pure water? Express your answer to three significant figures and include the appropriate units.
