Suppose that you wish to attempt the separation of Cu2+ from SbO+ by means of con- trolled-potential deposition of copper metal onto a platinum cathode. Assume that the original sample solution contains 1.00 M H+, 0.0325 M Cu2+, and 0.500 M SbO+, and that [H+] remains at 1.00 M throughout the course of the electrolysis. (a) At what potential (versus SHE) must the platinum cathode be controlled to cause 99.9% deposition of elemental copper? (b) What fraction of the SbO+ will be reduced to the elemental (Sb) state under the experimental conditions imposed in part (a)? (c) If the volume of the original sample solution is 100.0 mL, what will be the total weight gain (in milligrams) of the platinum cathode under the experimental conditions imposed in part (a)?
