Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. The voltage that is needed for electrolysis to occur is called the decomposition potential.
This tutorial explains electrolysis, the operation of electrolytic cells, and how electrical energy drives chemical change. See how electrolysis is used in industry, everyday technology, and key electrochemical processes.
In an electrolytic cell (right), an external power source supplies electrical energy, generating a potential difference that forces electrons to flow and drives a nonspontaneous redox reaction. Most electrolytic cells use a single compartment.
Electrolysis is a process where electrical energy is used to drive a non-spontaneous chemical reaction. The electrical energy provided is converted into chemical energy, driving the endothermic electrolytic reactions.
A familiar example of electrolysis is recharging a battery, which involves use of an external power source to drive the spontaneous (discharge) cell reaction in the reverse direction, restoring to some extent the composition of the half-cells and the voltage of the battery.
