Purifying Mg2+ from sea water. Aqueous sodium hydroxide is added to an aqueous solution that contains 0.0099 M magnesium chloride and 0.021 M calcium chloride. What will be the concentration of the metal ion that precipitates first (as M(OH)2) at the time the second metal ion begins to precipitate? Ksp (Mg(OH)2) = 6.3 x 10-10 and Ksp (Ca(OH)2) = 6.5 x 10-6 Hint: Use Ksp values to determine the solubility of each product to determine the order of precipitation.

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...
