Oxidation and reduction are chemical processes that involve the transfer of electrons. In oxidation, a substance loses electrons, and in reduction, it gains electrons.
Example:
Consider the reaction between iron (Fe) and oxygen (O2) to form iron oxide (Fe2O3), commonly known as rust.
1. Oxidation: Iron undergoes oxidation by losing electrons.

Explanation:
Oxidation and reduction are chemical processes that involve the transfer of electrons. In oxidation, a substance loses electrons, and in reduction, it gains electrons.
Example:
Consider the reaction between iron (Fe) and oxygen (O2) to form iron oxide (Fe2O3), commonly known as rust.
1. Oxidation: Iron undergoes oxidation by losing electrons.
[tex]\[ 4\text{Fe} \rightarrow 4\text{Fe}^{3+} + 12\text{e}^- \]
[/tex]
2. Reduction: Oxygen undergoes reduction by gaining electrons.
[tex]\[ 6\text{O}_2 + 12\text{e}^- \rightarrow 12\text{O}^{2-} \][/tex]
The overall reaction can be represented as:
[tex]\[ 4\text{Fe} + 6\text{O}_2 \rightarrow 2\text{Fe}_2\text{O}_3 \][/tex]
