- 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:
- Atoms&Molecules:
- Must always = 0
- Simple ions

- Redox reaction:
- Eg. Na+, Cl-, Al3+
- =Na= +1, Cl= -1, Al= +3
- Oxidation Numbers:
- Eg. Na, Cl, O2, N2
- Equal = to their charge.
- Simple ions
- Eg. Na+, Cl-, Al3+
- =Na= +1, Cl= -1, Al= +3
- Simple ions
- 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.
