Electrolysis of Molten Compounds


Electrolysis is a process whereby a compound is decomposed by an electric current. 
An electrolytic cell consists of two electrodes (anode and cathode) that are dipped in an electrolyte and connected to batteries


  • Electrodes are conductors of electricity. Electric current enters or leaves the circuit through the electrodes. 
  • Graphite or platinum is usually used as electrodes because they are inert (do not react with electrolytes or products of electrolysis).
  • Anode is the electrode connected to the positive terminal of the batteries. Anions (negatively-charged ions) in the electrolyte are attracted to the anode (positive electrode). 
  • Cathode is the electrode connected to the negative terminal of the batteries. Cations (positively-charged ions) in the electrolyte are attracted to the anode (negative electrode). 
  • All electrolytes will dissociate into cations and anions in the molten states or aqueous solutions.
