Question

Which among the following has carbon as the positive electrode?

• A. Leclanche
• B. Bichromate cell
• C. Dry cell
• D. All of the above

Answer 1

The correct option is D

All of the above

1. As carbon is a good conductor, it is a basic requirement of electrolysis.
2. Mostly it is used in the form of graphite.
3. So, Leclanche, Bichromate cell, and dry cell, all of them used carbon as the positive electrode.

Hence, the correct option is (D).
