What to Focus On
- Oxidation: loss of electrons
- Reduction: gain of electrons
- Redox reactions involve simultaneous oxidation and reduction
- Oxidation number is a bookkeeping tool for electron transfer
- Rules help assign oxidation numbers systematically
- Sum of oxidation numbers = 0 in neutral compounds, equals charge in ions
- Two methods: oxidation number and ion-electron
- Ion-electron method is more systematic for complex reactions
- In acidic medium, use H⁺ and H₂O; in basic, use OH⁻ and H₂O
Common Mistakes to Avoid
Oxidation always means adding oxygen, and reduction always means removing oxygen.
Oxidation number and charge are the same thing.
In a galvanic cell, electrons flow from cathode to anode.
Memory Tips
Oxidation is loss, reduction is gain (of electrons)
Anode is where oxidation occurs, cathode is where reduction occurs
Electrons flow from anode to cathode in external circuit
Rules for assigning oxidation numbers
