What Is Electrolysis

Electrolysis

In archaeological conservation, a cleaning process, especially of material from subaqueous archaeology, involving immersing the object in a chemical solution and deprivation a weak current between it and a contact metal grille. Corrosive salts move slowly from the object (cathode) to the grille (anode), leaving the artefact clean.

Electrolysis

In chemistry, the production of chemical changes by going away an electric current through a solution or molten salt (the electrolyte), resulting in the migration of ions to the electrodes: positive ions (cations) to the minus electrode (cathode) and negative ions (anions) to the positive electrode (anode). During electrolysis, the ions react with the electrode, either receiving or giving up electrons. The resultant atoms may be liberated as a gas, or deposited as a solid on the electrode, in amounts that are proportional to the amount of current passed, as observe by English chemist Michael Faraday.



For instance, when acidified water is electrolysed, hydrogen ions (H+) at the cathode receive electrons to form hydrogen gas;

Electrolysis

Removal of un motiveed vibrissa using an electric current. It can be very impressive in experienced hands, but is slow and therefore expensive.
