Question

Which of the following allotropic form of carbon is used for making electrodes ?

• A. Diamond
• B. Graphite
• C. Coke
• D. Coal

Answer 1

Answer:

B. Graphite

allotropic form of carbon used for making electrodes is Graphite.

Graphite is a good conductor of electricity and has a layered structure, where carbon atoms are arranged in layers of hexagonal rings. These layers can slide over each other, making graphite a useful material for electrodes in batteries, electrolysis, and other electrical applications.

It is commonly used in the following applications:

• Electrodes for electrochemical processes (e.g., in batteries, fuel cells, and electrolysis).

• Pencil leads, due to its soft and lubricating properties.

• Lubricants, as it can reduce friction due to its layered structure.

So, Graphite is indeed the correct allotropic form of carbon used for making electrodes.
