Electrolysis is done to stimulate a non-spontaneous reaction. Electrolysis can be used to separate a substance into its original components/elements.

Process:In Electrolysis, an electric current it sent through an electrolyte and into solution in order to stimulate the flow of ions necessary to run an otherwise non-spontaneous reaction.

Processes involving electrolysis include: electro-refiningelectro-synthesis, and the chloro-alkali process.
