Question

It's often suggested that solutions which transport and deposit metallic sulfides are alkaline. At ordinary temperatures, would galena dissolve appreciably in the alkaline solution to form Pb(OH)3^-? In this and similar questions, assume that "appreciable solution" means a concentration of at least 10^-5 m, which for most common metals is roughly equal to 1 ppm.

Assume {S^2-} = 1.25x10^-9 m
