  • Oxidation Numbers:
    • Atoms&Molecules:
      • Must always = 0
    • Redox reaction:
      • Is the reaction here both oxidiation and reduction takes place in the same equation.
    • For Compounds:
      • The sum of oxidation must equal to = 0
    • O.I.L R.I.G:
      • Oxidation Is Lost, Reduction Is Gained.
      • For electrons.
    • Complex Ions.
      • The sum of the reaction must equal to the charge of the ion.
      • When it has an ion it ill be a complex ion.
  • Atoms&Molecules:
    • Must always = 0
  • Simple ions

        • The sum of the reaction must equal to the charge of the ion.
        • When it has an ion it ill be a complex ion.
    • Eg. Na+, Cl-, Al3+
    • =Na= +1, Cl= -1, Al= +3
  • Eg. Na, Cl, O2, N2
    • Equal = to their charge.
      • Simple ions
        • Eg. Na+, Cl-, Al3+
        • =Na= +1, Cl= -1, Al= +3
    • Disproportiontion reaction:
      • Is where the species is oxidised and reduced in the same reaction.
    • Is where the species is oxidised and reduced in the same reaction.
