  • Electrolysis
    • AT THE POSITIVE ELECTRODE (called Anode)
      • The negative ions are attracted. They lose electrons to the electrode and turn into the element.
        • LOSING electrons is an oxidation reaction
    • AT THE NEGATIVE ELECTRODE (called Cathode)
      • The positive ions are attracted. They gain electrons from the electrode and turn into the element.
        • Gaining electrons is a reduction reation
    • = Passing electric current through an ionic liquid OR solution
      • To split up the compound into elements that are useful...
      • POSITIVE IONS  are attracted to the NEGATIVE ELECTRODE (cathode)
      • NEGATIVE IONS are attracted to the POSITIVE ELECTRODE (anode)
    • O I L   R I G
      • Oxidation Is Loss of electrons.       Reduction Is Gain of electrons.
    • PANIC
      • Positive= Anode, Negative Is Cathode
    • REMEMBER: Electrons move in a metal. Ions move in an ionic liquid or solution.
