At which electrode does oxidation occur in a voltaic cell?


Quick Answer

In a voltaic cell, the oxidation reaction occurs in the anode; this means the metal loses its electrons in this part while the other metal undergoes the reduction reaction and gains the anode's lost electrons. This redox reaction involves the transfer of electrons from one electrode to another.

Aside from electrodes, a voltaic cell is also composed of compartments called half-cells. Each cell consists of a piece of metal within a solution. The half-cells are linked together by the salt bridge, a tube filled with an electrolyte solution that allows the free flow of ions from the half-cells. A voltaic cell also includes an external circuit, which conducts the flow of electricity, and a load that utilizes that electricity into a function. The light bulb is a simple example of a load that can be powered by a voltaic cell.
