What is the potential difference between electrodes and electrolyte?

The potential difference between electrodes and the electrolyte in an electrochemical cell is often referred to as the  electrode potential. This term describes the voltage developed by the difference in the tendency of electrodes to lose or gain electrons when they are in contact with an electrolyte. Each electrode (anode and cathode) has its own electrode potential, and the overall potential difference of the cell is the difference between these two potentials.
