Question
Transcribed Image Text:It is desired to separate silver in a solution that is 0.0591 M Bio*, 0.120 M Cu²+, 0.0986 M Ag*, and 0.500 M HCIO, by
controlled-potential electrolysis.
Ag+(aq) + 1 e → Ag(s)
E° = 0.799 V
Cu?+ + 2 e- → Cu(s)
E° = 0.337 V
Bio*(aq) + 2 H*(aq) + 3 e
Bi(s) + H,O(1)
E° = 0.320 V
Between what cell potentials can silver be quantitatively removed from the solution without also removing one of the othe
ions using controlled-potential electrolysis? Use 1.00 × 10-6 M as the criterion for quantitative removal. Report all cell
potentials versus Ag|AgCl (E = 0.197 V). List the higher (more positive) potential first.
