Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.

Question

3. An acidic solution contains the ions VO₂+, Ce4+, Au³+ and Fe3+. Using the standard
reduction potential, (a) arrange these species in order of increasing oxidizing ability and (b)
predict which one will be reduced at the cathode of an electrolytic cell at the lowest voltage.
