Oxidation is a chemical process in which a substance loses electrons, increases its oxidation state, or gains oxygen. It is one half of a redox (reduction-oxidation) reaction, where oxidation and reduction occur simultaneously.
1. Rusting of Iron
When iron reacts with oxygen and water, it forms iron oxide (rust).
Example:Reaction:
4Fe+3O2→2Fe2O3
Here, iron (Fe) is oxidized to
Fe3+Fe3+in Fe2O3Fe2O3
Reduction is a chemical process in which a substance gains electrons, decreases its oxidation state, or loses oxygen. It is the opposite of oxidation and is one half of a redox (reduction-oxidation) reaction. Reduction and oxidation always occur together in a redox reaction.
Example:
2. Reduction of Iron Ore in a Blast Furnace
Iron ore (Fe2O3Fe2O3) is reduced to iron (Fe) using carbon monoxide (CO).
Reaction:
Fe2O3+3CO→2Fe+3CO2Fe2O3+3CO→2Fe+3CO2
