1. Consider the reaction: CuS Cu2+ + S2- The presence of common ion shifts the reaction (TOWARDS or AWAY FROM) the product side resulting in a/an (INCREASE or DECREASE) in the solubility of the ionic solid. 2. Which is/are TRUE considering the reaction below? NiCO3 Ni2+ + CO3 2- Is it, I. Dissolving NiCO3 in a 0.001 HCl solution will increase its solubility; or, II. Dissolving NiCO3 in a 0.001 M Ni(NO3)2 will increase its solubility.

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) BaSeO4, 0.0118 g/100 mL. (b) Ba(BrO3)2H2O, 0.30 g/100 mL. (c) NH4MgAsO46H2O, 0.033 g/100 mL. (d) La2(MoO4)3, 0.00179 g/100 mL
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.

Tooth enamel consists of hydroxyapatite, Ca5(PO4)3OH (Ksp = 8 × 10−37). Fluoride ion added to toothpaste and also drinking water reacts with Ca5(PO4)3OH to form the more tooth decay–resistant fluorapatite, Ca5(PO4)3F (Ksp = 1.0 × 10−60). Fluoridated water has dramatically decreased cavities among children. Calculate the solubility of Ca5(PO4)3OH and of Ca 5(PO4)3F in water.
