- Physical Chemistry. the passage of an electric current through an electrolyte with subsequent migration of positively and negatively charged ions to the negative and positive electrodes.
- the destruction of hair roots, tumors, etc., by an electric current.

The metals were first prepared by Davy in 1808 by electrolysis.
This is melted in an iron pot which also serves as the cathode in the electrolysis.
What metals and compounds studied are prepared by electrolysis?
This method may not be a cure for electrolysis, but will add to the life of the pipe.Elements of Plumbing
- the conduction of electricity by a solution or melt, esp the use of this process to induce chemical changes
- the destruction of living tissue, such as hair roots, by an electric current, usually for cosmetic reasons

Word Origin and History for electrolysis
- Chemical change, especially decomposition, that is produced in an electrolyte by an electric current.
- Destruction of living tissue, especially that of the hair roots, by means of an electric current applied with a needle-shaped electrode.
- A process in which a chemical change, especially decomposition, is brought about by passing an electric current through a solution of electrolytes so that the electrolyte's ions move toward the negative and positive electrodes and react with them. If negative ions move toward the anode, they lose electrons and become neutral, resulting in an oxidation reaction. This also happens if atoms of the anode lose electrons and go into the electrolyte solution as positive ions. If positive ions move toward the cathode and gain electrons, becoming neutral, a reduction reaction takes place. Electrolysis is used for many purposes, including the extraction of metals from ores, the cleaning of archaeological artifacts, and the coating of materials with thin layers of metal (electroplating).
