Question
![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,0*(aq)
