A transport truck carrying a load of 2000 kg of aluminum sulfate fell off a bridge after colliding with an errant beefalo. The transport dumped its entire load into a water reservoir that has a volume of 1.0 x 10' L. Aluminum sulfate is completely soluble in water. Aluminum ions are a health hazard linked to Alzheimer's disease. Environmentalists are concerned about just dumping the water, so they decide that it should be treated first and they come to you seeking your advice. a) Using the Kp table at the back of the exam, state which compound could be added to precipitate the aluminum ions. Explain your choice. b) Calculate the mass of the compound named in part a) that would have to be added to begin the precipitation. c) State one advantage and one disadvantage of treating the water prior to dumping.
