A solution contains 0.100 mM of Ni2+ and Zn2+. Hydroxyl ions are slowly added to this solution to precipitate either Ni(OH)2 or Zn(OH)2. Determine which ion precipitates first at the pH range from 0-14 and the range of OH- concentrations that will allow a clean separation of the two ions. Ksp for Ni(OH)2=6x10^-16 and for Zn(OH)2 Ksp=3x10^-16

    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...
