Electrolysis When chemical compounds are in a molten state, or if they are dissolved in water or other liquids their molecules become "separates into positively and negatively charged components, which have the conduct electricity", or they become ionized Electrolysis is the process of breaking down or 'decomposing' a compound, by running an electric current through a chemical compound when it is ionized. This is done using a simple circuit, as below: z When a pair of electrodes as above is placed in an ionized solution (Electrolyte) and there is a current flowing between them, the positive ions move toward the negative electrode - cathode and the negative ions move towards the positive electrode - anode. The ions that move towards the cathode are called "cations" and the ions that move toward the anode are called "anions". When the ions reach their respective electrodes, they gain or lose electrons and are transformed into...
