Description: Electrolysis is a chemical effect brought about by an electric current. A Direct current is used to Force a chemical reaction between two electrodes (a cathode and an anode) that are immersed in a conductive liquid (electrolyte). During electrolysis, the electrolyte is broken down into its components parts. The chemical reaction brought about by electrolysis can also be reversed. In this case, chemical energy is converted into electrical energy. Batteries are one well-known example of this process. Electrolysis takes place again if a battery is subsequently recharged. Technical applications of electrolysis include the following: Refining - obtaining high-purity aluminium, copper, silver or gold. Pure metal that was previously bound to the anode in an impure state is deposited on the cathode. Electroplating - applying a protective layer of metal, e.g. chrome or Nickel plating. Water cleavage - splitting water into hydrogen and oxygen. Electrolytic polishing - e.g. in medical applications to reduce the adhesion of bacteria. Deburring - mechanical deburring is often not possible on complex workpieces. Anodising - applying an oxide layer to aluminium.
