Question:
In which of the following metal extraction, \( CO_2 \) is used?
In which of the following metal extraction, \( CO_2 \) is used?
Show Hint
The extraction of aluminum involves electrolytic reduction of aluminum oxide, and \( CO_2 \) is released at the anode.
Updated On: Mar 17, 2025
- \( \text{Cu} \)
- \( \text{Zn} \)
- \( \text{Fe} \)
- \( \text{Al} \) \
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
In the extraction of metals, \( CO_2 \) is used in the extraction of aluminum. This is because, during the electrolysis of aluminum oxide, \( CO_2 \) is formed as a by-product at the anode.
In aluminum extraction, carbon electrodes are used, and at high temperatures, \( CO_2 \) is formed as a result of the reaction.
