What is the pH of the saturated solution of Ca(OH)2 (Ksp = 1.3 x 10-6). 12.14 8.11 11.06 12.37 2. To a 1.00 L solution containing 1.00 x 10-3 mole each of Ca2+, Sr2+, and Ba2+, 0.0100 mole of Na2SO4 solid is added. Ksp's for CaSO4, SrSO4, and BaSO4 are 6.1 x 10-5, 3.2 x 10-7, 1.5 x 10-9, respectively. Only BaSO4 will precipitate No precipitate will form Only BaSO4 and SrSO4 will precipitate All sulfates will form precipitate
