Can a voltaic cell in which both half-reactions are the same generate a current? O Yes, if there is a difference in concentration of the ion between the two half- reactions. Yes, electrons always flow toward the electrode with the more positive standard reduction potential. O No, if there is no difference in standard cell potential between the half- reactions, there can be no driving force for electrons to flow. Yes, as long as any two half-cells are connected by a salt bridge, a current will flow.

Concept explainers

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.
