Difference Between Active and Inert Electrodes
Jun 01, 2017· What is an Inert Electrode? Inert electrode is a metal that does not take part or interfere in any chemical reaction. But it is still used to conduct electricity by transferring electrons with the solution rather than exchanging ions with the solution. Therefore, it serves as an electron. Platinum is used as an inert electrode. But graphite is used widely because it is cheap.
