Electrolysis

Description

An electrochemical process caused when an electric current is passed between two electrodes in an aqueous solution. Water and any inorganic compounds in the solution will dissociate to form positive and negative ions that are then attracted to the electrodes of opposite charge. Any metallic ions in the solution will deposit as a coating on the electrode (see electroplating).
