Chapter 24, Problem 24.5QAP

What cathode potential (versus SCE) would be required to lower the total Hg(II) concentration of the following solutions to 1.00 × 10-6 M (assume reaction product in each case is elemental Hg):
(a) an aqueous solution of Hg2+?
(b) a solution with an equilibrium SCN- concentration of 0.100 M?
  Hg2+ + 2SCN- ⇌ Hg(SCN)2(aq) = Kf = 1.8 × 107
c) a solution with an equilibrium Br- concentration of 0.100 M?
  HgBr42++ 2e- ⇌ Hg(l) + 4Br- E0= 0.223 V
