Inert Electrode

When do we have to add an inert electrode to a cell diagram?

You add an inert platinum electrode whenever there is no solid substance in a half-cell. For example, for the standard hydrogen electrode, aqueous hydrogen ions are reduced to hydrogen gas, so since there is no solid substance to serve as the electrode, which is why an inert platinum electrode is needed.

Without an inert solid metal conductor, a cell with only aqueous ions would not be able to transfer electrons from the anode to the cathode.

Additionally if there is no solid in the reactant and product side, you must add it to both.

Also, inert electrodes like platinum do not participate in the redox reaction and are present so that current can flow through the cell.
