The electrode potential measures the tendency of the electrode to get oxidised or reduced. There is a potential difference between the electrode and the electrolyte called the potential of the electrode. When unity is the concentrations of all the species involved in a semi-cell, the electrode potential is known as the standard electrode potential.
Electrode potential is the tendency of an electrode to accept or to lose electrons. The potential of an electrode is the potential difference between it and the electrolyte surrounding the electrode. The value of electrode potential developed on an electrode depends on the following factors
- The concentration of ions in solution
- The temperature of the system
- Chemical nature of the metal or nonmetal
- A number of electrons transferred in the half cell reactions.
- It does not depend on the electrode.
