Which of the following statements is not correct about an inert electrode in a cell?

Options

A. It does not participate in the cell reaction
B. It provides surface either for oxidation or for reduction reaction
C. It provides surface for conduction of electrons
D. It provides surface for redox reaction

Answer

D

Explanation

The inert electrode is an electrode that serves only as a source or sinks for electrons. Precious metals, mercury, and carbon are typically used as inert electrodes. It provides a surface for oxidation or reduction reaction but not for the redox reaction. It does not participate in the cell reaction.
