To determine the solubility product constant of Al(OH)3 at a specific temperature, a saturated solution of Al(OH)3 at the required temperature was titrated with 0.2M HCl via the reaction: 3HCl + Al(OH)3  → AlCl3 + 3H2O.  Based on the following data, determine the Ksp of Al(OH)3 at the specified temperature:                Volume of Al(OH)3 titrated: Volume of 0.2M HCl required: 9.5 mL 3.44 mL Your answer should follow the format: a) mols of HCl added b) mols of Al(OH)3 c) Molarity of Al(OH)3 d) Ksp of Al(OH)3

A highly acidic (pH< 0.5) industrial wastewater has an initial AlP" concentration of 10 ppm. An engineer decides that strong base should be added to the wastewater in order to raise the pH so that most of the aluminum will precipitate and be removed from solution. The pertinent solubility reaction from Appendix A of our text is: Al(OH)3 (s) → Al* + 30H¯ with pK, = 32.9 a. What is the lowest pH needed to precipitate all but 50 ppb of the aluminum from the wastewater? Assume equilibrium conditions can be achieved. b. Suppose the engineer decides that the pH should be raised to 7. What equilibrium concentration of aluminum would be left in solution? Report your answer in ppb and moles per liter.
