  • Electrolysis
    • Oxidation= Gain of Oxygen and loss of Electrons
    • Reduction= Loss of Oxygen and gain of Electrons
    • Displacement.More reactive metal loses electrons and is oxidised. Less reactive metal gains electrons and is reduced
    • Splitting up with electricity.
    • Positive ions move to negative Cathode. Reduced
    • Negative ions move to positive anode. Oxidised
    • Molten or dissolved ionic compound
    • Electrodes made from graphite. Electric current passed through an electrolyte
    • Creates a flow of Charge
    • Hydrogen gas produced at the Cathode if metal ion is more reactive than hydrogen
