  • Electrolysis
    • Definitions
      • Electrolysis= electrical energy from a DC supply decomposes compounds
      • Electrolyte= substance which conducts electricity
        • Solution e.g. NaCl
        • Moltern e.g. moltern lead bromide
      • Electrode= conducts electricity into and out of the  electrolyte
        • intert metals, usually graphite (cheap + readily available
    • Electrodes
      • Anode
        • Positive +
        • Attracts negative ions
          • Positive +
      • Cathode
        • Negative -
        • Attracts positive ions
          • Negative -
      • Graphite
        • inert
        • Cheap
      • Coppers
        • Purification of copper
      • Silver
        • Electroplating
    • discharging
      • Lose their charge and become atoms
      • Rule: ion discharged must give the leaast reactive element
