what is an inert electrode

An inert electrode is a conductor that lets electrons pass in an electrochemical cell without taking part in the reaction itself. Common examples are platinum and graphite.

Quick Scoop

• What it does: Provides a surface for oxidation or reduction to happen.

• What it does not do: It does not get used up or chemically changed in the reaction.

• Common materials: Platinum, graphite, and sometimes gold.

Why it matters

Inert electrodes are used when the reacting substances are only in solution or in gas form, so you need a stable conductor to complete the circuit. They help avoid unwanted side reactions and keep the cell focused on the intended redox process.

Example

A common example is electrolysis of water , where graphite or platinum can be used as an inert electrode.
