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, O(1) = s²-(aq) + 2 H,O*(aq) Keq = 1.1 × 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 Kp of PbS is 8.9 × 10-29. [s-] = M %3D Above what concentration of S2- will Ag, S precipitate? The Ksp of Ag, S is 3.3 x 10-50. [s-] = M %3D 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
