  • Electrolytic Process
    • CONDITIONS
      • Ions that are free to move
      • Posotive and negetive electode
      • Power Supply
      • Electolyte: Ionic substunce that conducts the electricity when Aqueus/Molten
    • WHAT IS IT?
      • When ionic substances are broken down when a current is pass through
    • O.I.L.R.I.G.
    • ANIONS & CATIONS
      • ANIONS
        • Negatively charged so they are attracted to the ANODE
        • At the anode they LOOSE Electrons (Oxidisation)
      • CATIONS
        • Posotively charged ions so they are attracted to the CATHODE and Gain electrons  (Reduction)
    • Electrolysis of COPPER CHLORIDE
      • CATHODE
        • Copper Ions
        • Gain 2 Electrons
        • Half Equation:
        • Forms Copper wiich appears brown (Solid) at the electrode
      • ANODE
        • Chloride ions
        • Loose an electron
        • Chlorine atoms join up (Cl2)
        • Gas
        • Half Equation:
    • LEAD BROMIDE
      • CATHODE
        • Lead is forced to gain 2 electrons
        • Forms a liquid
        • Half equation
      • ANODE
        • Bromine ions loose an electron
        • Form diatomic bromine molecules
        • Brown gas at electrode
        • Half Equation
