Question

What is the electrode in the center of the most common dry cell made of?

Answer 1

A common dry-cell battery is the zinc-carbon battery, which uses a cell that is sometimes called the Leclanché cell. The cell is made up of an outer zinc container, which acts as the anode.

Answer 2

Graphite

Step-by-step explanation:

An electrode is a solid electric conductor (usually metallic) used in electrolytic cells for carrying electric current. An electrolytic cell is made up of electrodes and electrolytes. There are two types of electrodes

• Anode - attracts negatively charged ions (anions)
• Cathode - attracts positively charged ions (cations)

The common dry cell is the transistor battery. The cylindrical coating of this cell is made up of zinc which serves as the anode while the center electrode which is the graphite is the cathode. Graphite is one of the allotropes of carbon and it is a good conductor of electricity.

An electrolyte is a liquid/aqueous solution that allows the passage of electric current. The electrolyte in this cell is usually made up of manganese dioxide (MnO₂), carbon powder and ammonium chloride (NH₄Cl).
