It is desired to separate bismuth, copper, and silver in a solution that is 0.0562 M BIO+, 0.125 M Cu²+, 0.0986 M Ag+, and 0.500 M HCIO by controlled-potential electrolysis. Ag+ (aq) + le → Ag(s) Cu²+ + 2e Cu(s) BIO+ (aq) + 2 H+ (aq) + 3 e Bi(s) + H₂O(1) Determine the cell potential at which each ion begins to deposit on the cathode. Report all cell potentials versus Ag/AgCl (E = 0.197 V). Ag+ Ecell = Cu²+ Ecell = BIO+ Ecell = Ag+ Cu²+ Ecell = Ecell = 0.245 Incorrect 0.111 Incorrect Determine the cell potential at which each ion is quantitatively removed from the solution. Use 1.00 x 10-6 M as the criterion for quantitative removal. Report all cell potentials versus Ag/AgCl (E = 0.197 V). Incorrect BIO+ Ecell = 0.040 Incorrect E = 0.799 V E = 0.337 V E = 0.320 V -0.009 Incorrect V V V V V V
