What is the Difference Between Metallic and Electrolytic Conduction?

The main difference between metallic and electrolytic conduction lies in the nature of the substances involved and the way they conduct electricity. Here are the key differences between the two:

1. Nature of the substances: Metallic conduction involves the movement of electrons through metals, such as aluminum, silver, or tin. In contrast, electrolytic conduction involves the movement of ions (charged atoms or molecules) through a pure liquid or solution, such as acids, bases, and salts.
2. Chemical changes: Metallic conduction is a physical process that does not involve any chemical change. On the other hand, electrolytic conduction is both a physical and chemical change, as ions move through the electrolyte, and chemical reactions occur at the electrodes.
3. Temperature dependence: Metallic conduction decreases with an increase in temperature. In contrast, electrolytic conduction increases with an increase in temperature.
4. Transfer of matter: In metallic conduction, there is no transfer of matter. In electrolytic conduction, however, there is a transfer of matter as ions move from one electrode to another.

In summary, metallic conduction is the movement of electrons through metals without any chemical change, while electrolytic conduction involves the movement of ions through a solution or liquid, accompanied by chemical reactions at the electrodes.

Comparative Table: Metallic vs Electrolytic Conduction

Here is a table comparing the differences between metallic and electrolytic conduction:

In summary, metallic conduction involves the movement of free electrons through metals, while electrolytic conduction involves the movement of ions through a pure liquid or solution. Metallic conduction is a physical process that does not result in the formation of new substances, whereas electrolytic conduction involves both physical and chemical changes. The temperature dependence of these conductions is also different, with metallic conduction decreasing and electrolytic conduction increasing with an increase in temperature.
