Q. 5

Which of the following statement 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.

Class 12th Chemistry - Exemplar 3. Electrochemistry

Answer :

Inert electrodes are made of less reactive metals such as gold and platinum, which do not participate in the electrochemical reaction but provide a surface for the reactions to occur. Their surface is provided for either oxidation or reduction reactions or for conduction of electrons. Redox reactions, a combination of oxidation and reduction cannot occur on the surface. The correct option is (iv).
