Blister copper is:
Show Hint
- Impure Cu
- Cu alloy
- Pure Cu
- Cu having 1\% impurity
The Correct Option is D
Solution and Explanation
Step 1: Understanding blister copper.
- Blister copper is the intermediate product in the extraction of copper.
- It is obtained after the Bessemerization process, where molten copper is oxidized to remove iron and sulfur impurities.
Step 2: Composition of blister copper.
- It contains about 98-99\% pure copper with 1-2\% impurities like oxygen and sulfur.
- The name "blister copper" comes from the blisters formed due to escaping sulfur dioxide (\( SO_2 \)) gas.
Step 3: Identifying the correct answer.
- Since blister copper has 1\% impurity, the correct option is (D).
