You would like to investigate the experimental solubility of Ca(OH)2 at 25 degrees Celsius in the presence of the common ion. In the experiment, you dissolve Ca(OH)2(s) into a 100mL solution containing 2.00 g of dissolved CaCl2. The saturated Ca(OH)2 solution has an equilibrium pH of 11.68. Determine the molar solubility and the Ksp, for Ca(OH)2 from this single pH measurement.
