Metal sulfides are prepared by bubbling hydrogen sulfide gas, H, S, through an aqueous solution containing the metal ion, and then adjusting the pH. When the solution is saturated with H, S, which occurs when [H, S] = 0.100 M, the equilibrium shown is established. H,S(aq) + 2 H,O1) = s²-(aq) + 2H,O*(aq) Keg = 1.1 x 10-20 An aqueous solution containing 0.0117 M Pb2+ and 0.0117 M Ag+ is saturated with H, S. Above what concentration of S2- will PbS precipitate? The Ksp of PbS is 8.9 x 10-29. [s²-] = M Above what concentration of S2- will Ag, S precipitate? The Kp of Ag, S is 3.3 x 10-50. [s²-] = M If the pH of the solution is adjusted to 2.73, which species will precipitate from the saturated H, S solution? neither species PbS both PbS and Ag,S Ag, S

Swimming pool disinfectants produce hypochlorous acid upon dissolution. The weak acid ionizes as follows: HClO (aq) ⇄ H+ (aq) + ClO‒ (aq) Ka=3.0 x 10 ‒8 As strong oxidizing agents, both acid and its conjugate base kill bacteria. However, too high [HClO] is irritating to swimmers’ eyes and too high [ClO‒] will cause the ions to decompose in sunlight. The recommended pH to circumvent both problems is 7.8. Determine the ratio of the weak acid and its conjugate base at this pH.
