A potential difference develops between the electrode and the electrolyte which is called

The correct answer is Electrode Potential.

Key Points

• Electrode potential is the potential difference developed between an electrode and its surrounding electrolyte due to the tendency of the electrode to gain or lose electrons.
• The electrode potential is measured relative to a reference electrode, commonly the Standard Hydrogen Electrode (SHE).
• Electrode potential is a fundamental concept in electrochemistry and is used to determine the feasibility and direction of redox reactions.
• It can be expressed as standard electrode potential when measured under standard conditions (298 K temperature, 1 M concentration, and 1 atm pressure).
• The sign of the electrode potential indicates whether the electrode acts as an anode (oxidation occurs) or a cathode (reduction occurs).

Additional Information

• Cell Potential: The overall voltage of an electrochemical cell, calculated as the difference between the cathode and anode electrode potentials.
• Electromotive Force (EMF): The maximum potential difference between two electrodes of a cell when no current flows through the cell.
• Standard Electrode Potential (E°): The electrode potential measured under standard conditions, used as a reference to predict reaction spontaneity.
• Redox Reaction: A chemical process involving the transfer of electrons between two species, forming the basis for electrochemical cell reactions.
• Reference Electrode: An electrode with a stable and well-defined potential, such as the Standard Hydrogen Electrode (SHE), used for comparison in electrochemical measurements.
