Examples of Redox Reaction

1. Combustion of metal in oxygen
2. Reaction between metal oxide and carbon
3. Reaction between metal oxide and hydrogen
4. Conversion of Fe²⁺ ion to Fe³⁺ and vice versa
5. Displacement of metal from their salt solution
6. Displacement of halogen
7. Transfer of electron at a distance
8. Rusting of iron
9. Electrolysis of aqueous solution & molten compound
10. Chemical cells

Tips : Students should be able to identify

1. oxidized substance and reduced substance
2. oxidizing agent and reducing agent all all those reactions

   and explain in terms of

1. gain/loss of electrons
2. change in oxidation number

Besides, the skill of writing chemical equation, half equation and overall ionic equation is too very very important.
