In the process of electrolysis, electrodes are used as conducting poles through which an electric current enters or leaves an electrolyte. Electrodes are made up of metals or graphite. The two electrodes are anode and cathode. The electrode connected to positive terminal of the battery is called anode. Current enters the electrolyte through anode. Anions migrate towards anode and are discharged here. The electrode connected to the negative terminal of the battery is called cathode. Current leaves the electrolyte through cathode. Cations migrate towards cathode and are discharged here.
