    • electrolysis
      • electrolysis is the breaking down of a compound using electricity
      • an ionic compound can only be electrolysed when it is molten or in a solution in water
      • when a molten ionic compound is electrolysed, a metal is formed at the negative electrode and a non-metal at the positive electrode
    • explaining electrolysis
      • in electrolysis, metals or hydrogen are formed at the negative electrode and halogens or oxygen are formed at the positive electrode
      • during electrolysis ions gain electrons at the cathode (negative) and gain electrons at the anode (positive)
