Gypsum is a relatively soft rock made of CaSO4. Rainwater percolates through gypsum, dissolves some of the rock, and eventually becomes saturated with Ca2+ ions and SO2- ions. A geochemist takes a sample of groundwater from a cave and finds that it contains 8.4 x 10-3 M SO2- and 5.8 x 10-3 M Ca²+. (The ratio is not 1:1 because other sulfate rock contributes some of the SO42- ions to the solution.) Use these data to determine the solubility product of CaSO4.

1. Use the AG = AH – TAS relationship to justify why the solubility of KOH(s) in water decreases as temperature is increased. Do not do any calculations. (HINT: the S° value for KOH(s) is greater than that for KOH(aq).)
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.

The Hydratres of Chromium(III) chloride have 3 known forms: A is a hexahydrate, B is a pentahydrate, C is a tetrahydrate. Adding excess of silver ion to a solution of 1 mole of each results in the following precipitates of silver chloride. A 3 moles, B 2 moles, C 1 mole. Using this information deduce the actual structure of each hydrate and write the corresponding name.
15). If Ca(NO3) (aq) is slowly added to solution containing CO32– and SO42– what compound would precipitate out first given the solubility products (Ksp (CaSO4) = 2.4 x 10–5 and Ksp (CaCO3) = 8.7 x 10–9)? CaCO3 would precipitate first because it is least soluble. CaSO4 would precipitate first because it is least soluble. CaCO3 would precipitate first because it is more soluble. CaSO4 would precipitate first because it is more soluble.
