Fe3+ ions are to be separated from Hg2+ ions from an aqueous solution in which their concentrations are both 0.05500 M . The criterion for "complete" separation is that the Fe3+ ion concentration must be 10,000 times larger or 10,000 times smaller that the Hg2+ ion concentration. Answer the questions below. At what pH will Fe(OH)3 precipitate from a 0.05500 M Fe3+ solution? Ksp = 2.800×10-39 At what pH will Hg(OH)2 precipitate from a Hg M Hg2+ solution? Ksp = 3.100×10-26...

2nd part only the pH is correct.
Metal ions in aqueous solutions are solvated, or hydrated, by water molecules. Typically this primary hydration sphere is composed of six water molecules. The hydrated metal ion acts as a weak acid, undergoing a stepwise hydrolysis in which it donates an Htion from its water ligands to the surrounding free water molecules. Shown is the hydrolysis of Al(H,0) (pKA = 4.85) in water. Al(H,0)(aq) + H20(1) - 1,0+ (aq) + Al( HO), OH...
