Detailed Solution

An inert electrode is an electrode that does not take part in a chemical reaction and only conducts electricity. In electrochemistry, electrodes are used to transfer current in electrolytic solutions. Some electrodes, like copper or zinc, react chemically. But inert electrodes are chemically inactive. They simply act as a medium for passing current and do not change themselves.

Examples of Inert Electrodes

Platinum (Pt)
Graphite (Carbon)
Gold (in some cases)

Uses of Inert Electrodes

Electrolysis of water uses graphite as electrodes.
Platinum electrodes are used in fuel cells.
Used in electroplating where reaction should involve only ions of electrolyte.

Why Are They Important?

They prevent unwanted side reactions and ensure only the desired ions take part in the process. This is why inert electrodes are used in industries for purity.
