A fermenter was filled with 10L of 0.6 mol/L sodium sulfite solution containing 0.003M Cu2+ ion and the air sparger was turned on. After exactly 10 minutes, the airflow was stopped and a 5 mL sample was taken and titrated. The concentration of sodium sulfite in the sample was found to be 0.2 M. Calculate the oxygen uptake rate.

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.
