Blister copper is : — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

Step 1: Blister copper is the direct product obtained from the Bessemer converter during the self-reduction of copper sulfide. Step 2: As the molten copper cools, dissolved sulfur dioxide (SO2) gas escapes, leaving blister-like bubbles on the surface. Step 3: It contains about 98% copper and 2% impurities, making it a form of impure copper. Thus, option (d) is correct.
