The Handbook of Chemistry and Physics (http://openstaxcollege.org/l/16Handbook) gives solubilities of the following compounds in grams per 100 mL of water. Because these compounds are only slightly soluble, assume that the volume does not change on dissolution and calculate the solubility product for each. (a) BaSiF6, 0.026 g/100 mL (contains SiF62- ions) (b) Ce(IO3)4, 1.5102 g/100 mL (c) Gd2(SO4)3, 3.98 g/100 mL (d) (NH4)2PtBr6, 0.59 g/100 mL (contains PtBr62- ions)

One way to reduce the presence of lead in water is to add a phosphate corrosion inhibitor, which forms an insoluble saltwith lead, coating the pipes with a protective mineral later: Pb3(PO4)2(s) ⇌ 3Pb2+(aq) + 2PO43-(aq) Kc=9.9 x 10-55 a.) Calculate the solubility of lead (Pb2+) in g/L when Pb3(PO4)2 is dissolved in water. b.) The acceptable level of lead in water is less than 1x10-6g/L. If phosphate is added to drinking water, does it keep the lead levels below the allowed limit? c.) In 2014, the city of Flint, MI, changed water sources to a system that didn’t include phosphate. Instead, it used chlorine to treat water. The Ksp of lead chloride is 1.5x10-5. The switch increased the levels of lead in the drinking water and significantly affected the community. Explain why switching water sources increased the lead levels in Flint’s drinking water.
Suppose 234.3 mg of PbCl2 was added to 16.0 mL of water in a flask, and the solution was allowed to reach equilibrium at 21.0 oC. Some solute remained at the bottom of the flask after equilibrium, and the solution was filtered to collect the remaining PbCl2, which had a mass of 91.6 mg . What is the solubility of PbCl2 (in g/L)? -Express the concentration in grams per liter to three significant figures.

There is a solution containing two metal cations. The goal is to separate them by slowly and carefully adding a solution of an anion, until one mental cation precipitates as a compound with that anion, leaving the other metal cation still in solution. M+ is Ag+, M2+ is Ca2+, anion is SO4 2-, first Ksp is 1.2 x 10-5, second Ksp is 6.1 x 10-5, and the starting concentrations of M+ is 1.50 x 10-2 M and M2+ is 3.50 x 10-2M. Using these values, predict which metal will precipitate first and what concentration of anion the precipitation will begin.
