electrolytic cell
An electrolytic cell is an electrochemical cell that uses electrical energy to
drive a non-spontaneous chemical reaction. Unlike galvanic cells, which
generate electrical energy from a spontaneous redox reaction, electrolytic
cells require an external power source to drive the reaction in the opposite
direction. Electrolytic cells are widely used in various industrial processes,
such as electroplating, metal refining, and the production of chemicals.
The basic components of an electrolytic cell include two electrodes, an
electrolyte solution, and an external power source (such as a battery or
power supply). The electrodes can be made of any conductive material,
such as metal or graphite, and they are typically connected to the power
source by wires. The electrolyte solution contains ions that can be reduced
or oxidized, and it allows the transfer of these ions from one electrode to
the other.
As an example, consider the electrolysis of water, which is the process of
splitting water molecules (H2O) into their constituent elements, hydrogen
and oxygen. This reaction is non-spontaneous, meaning that it requires an
external energy input to occur. In an electrolytic cell, two electrodes
(usually made of platinum) are submerged in a solution of water and an
electrolyte, such as sulfuric acid. The electrodes are connected to a power
source, which provides a direct current (DC) of electricity to the cell.
