- Combustion of metal in oxygen
- Reaction between metal oxide and carbon
- Reaction between metal oxide and hydrogen
- Conversion of Fe2+ ion to Fe3+ and vice versa
- Displacement of metal from their salt solution
- Displacement of halogen
- Transfer of electron at a distance
- Rusting of iron
- Electrolysis of aqueous solution & molten compound
- Chemical cells
Tips : Students should be able to identify
- oxidized substance and reduced substance
- oxidizing agent and reducing agent all all those reactions
and explain in terms of
- gain/loss of electrons
- change in oxidation number
Besides, the skill of writing chemical equation, half equation and overall ionic equation is too very very important.
