The tendency of an electrode (substance) to lose or gain electrons when it is in contact with its own ions is called electrode potential (E°). The magnitude of standard electrode potential values depends upon On the following factors EXCEPT:

Explanation

The correct answer is Surface area of the electrode. The standard electrode potential is a measure of the tendency of a chemical species to be reduced and is an intrinsic property that does not depend on the surface area of the electrode. Surface area affects the rate of reaction but not the potential itself.Nature of electrode and the ions is incorrect because the specific materials and ions involved do influence the standard electrode potential.Concentration of the solution in which the electrode is placed is incorrect because the concentration of ions can alter the potential by shifting the equilibrium of the reaction taking place at the electrode surface.The temperature of the cell is incorrect because temperature changes can affect the kinetic energy of particles, thus influencing the electrode potential.
