Unformatted text preview: solubility equilibrium is established. a. What is the molar solubility of AgCl? b. More water is added to the flask. When the solubility equilibrium is reestablished, does the molar solubility change? Does the amount of solid AgCl left in the flask change? 5. Find the molar solubility of BaCrO 4 ( K sp = 2.1 x 10-10 ) in a. pure water [S = 1.4 x 10-5 M] b. 1.5 x 10-3 M Na 2 CrO 4 [S = 1.4 x 10-7 M] 6. Does any solid PbCl 2 form when 3.5 mg of NaCl is dissolved in .250 L of 0.12 M Pb(NO 3 ) 2 ? As you solve this problem, write out the reaction equation that is being examined. [no solid will form] 7. The solubility of calcium sulfate is 0.209 g per 100. mL solution at 20 C. Calculate its K sp . [2.36 x 10-4 .]...
