Question

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

• 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 1

Answer: (D)

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.
