  • Electrolysis
    • Oxidation and Reduction
      • OIL RIG
        • Oxidation Is Loss
          • (of electrons)
            • Reduction Is Gain
        • Reduction Is Gain
    • Splitting by Electricity
      • To split aluminium from its ore, you need to add CRYOLITE
        • Na3AlF6 = Cryolite
        • Reduces the melting point to 700 degrees
        • Al3+ ADD 3e- --> Al (Redox)
          • 2O2- --> O2 + 4e- (Oxidation)
        • 2O2- --> O2 + 4e- (Oxidation)
    • Two electrodes in a solution
      • + Electrode = Anode
        • Negatively charged substance is attracted to the anode
      • - Electrode = Cathode
        • Positivley charged substance is attracted to the cathode
          • Negatively charged substance is attracted to the anode
    • Electrolysis is useful for separating substances from unwanted ones
      • Aluminium ore - aluminuim
      • Salt - Hydrogen, Sodium Hydroxide and Chlorine
