Identify the substances that are oxidised and the substances that are ...
To identify the substances that are oxidized and reduced in the given reaction:
Reaction: Fe2O3 + 2Al → Al2O3 + 2Fe
- Oxidation involves the loss of electrons.
- Reduction involves the gain of electrons.
- Iron (Fe) in Fe₂O₃:
- In Fe₂O₃, iron is in the +3 oxidation state.
- In elemental Fe, the oxidation state is 0.
- Thus, Fe is reduced from +3 to 0.
- Aluminum (Al):
- In elemental Al, the oxidation state is 0.
- In Al₂O₃, aluminum is in the +3 oxidation state.
- Thus, Al is oxidized from 0 to +3.
Substances:
- Substance reduced: Fe₂O₃ (iron is reduced to Fe).
- Substance oxidized: Al (aluminum is oxidized to Al₂O₃).
Correct Answer: (d) Both A and B
Explanation: Fe₂O₃ is reduced, and Al is oxidized.
Explanation: Fe₂O₃ is reduced, and Al is oxidized.

Identify the substances that are oxidised and the substances that are ...
Understanding Oxidation and Reduction
In a chemical reaction, oxidation refers to the loss of electrons, while reduction involves the gain of electrons. These processes are often coupled, meaning that one substance is oxidized while another is reduced.
Analyzing the Reaction
The reaction given is:
Fe2O3 + 2Al → Al2O3 + 2Fe
To determine which substances are oxidized and reduced, we need to analyze the changes in oxidation states.
Oxidation State Changes
- Fe2O3 (Iron(III) oxide):
- Iron (Fe) has an oxidation state of +3 in Fe2O3.
- After the reaction, iron is reduced to elemental iron (Fe), which has an oxidation state of 0.
- Al (Aluminum):
- Aluminum (Al) in this reaction starts with an oxidation state of 0 (elemental form).
- After the reaction, it forms Al2O3, where aluminum has an oxidation state of +3.
Identifying Oxidized and Reduced Substances
- Oxidation:
- Aluminum (Al) is oxidized from 0 to +3, meaning it loses electrons.
- Reduction:
- Iron (Fe) in Fe2O3 is reduced from +3 to 0, meaning it gains electrons.
Conclusion
In this reaction:
- Fe2O3 is reduced (iron is reduced).
- Al is oxidized (aluminum is oxidized).
Therefore, the correct answer is option ‘D’: both Fe2O3 and Al participate in oxidation and reduction processes.
