Question

The reaction that takes place in Thermite process is

• A. Reduction
• B. Oxidation
• C. Neutralisation
• D. None of the above

Answer 1

The Correct Option is A

To solve this problem, we need to understand the chemical reaction that occurs during the Thermite process.

1. The Thermite Reaction:
The Thermite process involves a reaction between a metal oxide (usually iron(III) oxide) and a more reactive metal (typically aluminum). The reaction is highly exothermic and results in the reduction of the metal oxide and the production of molten metal. The reaction is as follows:

\( \text{Fe}_2\text{O}_3 + 2\text{Al} \rightarrow 2\text{Fe} + \text{Al}_2\text{O}_3 \)

2. Nature of the Reaction:
In this reaction, aluminum (Al) reduces iron(III) oxide (Fe₂O₃) to produce iron (Fe), while aluminum is oxidized to form aluminum oxide (Al₂O₃). Therefore, the reaction is a reduction reaction.

3. Evaluating the Options:
(A) Reduction – Correct ✅ (The reaction involves the reduction of iron(III) oxide by aluminum.)
(B) Oxidation – Incorrect (Although oxidation occurs for aluminum, the overall reaction is reduction.)
(C) Neutralisation – Incorrect (Neutralisation is not involved in this reaction.)
(D) None of the above – Incorrect

Final Answer:
The correct option is (A) Reduction.
