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.

Question

Consider this cell running under standard conditions:
Ni(s) | Ni²+ (aq) || Cu*(aq) | Cu(s)

CIs this cell a voltaic or an electrolytic cell? How do you know?
O Since the cell potential is negative, the reaction is spontaneous, and the cell is an
electrolytic cell.
O Since the cell potential is positive, the reaction is spontaneous, and the cell is a
voltaic cell.
O Since the cell potential is positive, the reaction is spontaneous, and the cell is an
electrolytic cell.
O Since the cell potential is negative, the reaction is spontaneous, and the cell is a
voltaic cell.
