# Electrolysis

The use of electric current to stimulate a non-spontaneous reaction. Electrolysis can be used to separate a substance into its original components/elements and it was through this process that a number of elements have been discovered and are still produced in today's industry. 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-refining, electro-synthesis, and the chloro-alkali process.

## Electrolytic Cell vs Voltaic Cell

Example: When we electrolyze water by passing an electric current through it, we can separate it into hydrogen and oxygen.

$2 H_2O(l) \rightarrow 2H_2(g) + O_2(g)$
