- Meaning of ElectrodeElectrodes are conductors, in the form of wires, rods or plates, through which current enters and leaves the electrolyte. When the current leaves the electrodes it is known as the cathode... More Potential

- Copper(II) ions/Copper System
- Standard Electrode Potential
Electrode potential is the potential difference set up between an element and a solution of its ions.
Electrode potential is also the tendency of a metal to get oxidized or reduced when it is placed in a solution of its own salt.
When a metal (M) is placed in a solution containing its ions (M+ ) (for example a solution of one of its salts), then the metal may undergo oxidation, and then the positive metal ions may pass into the solution.
M(s) → M+ (aq) + e–
But if the metal undergoes reduction, then the solution will gain electrons from the metal and deposit themselves as neutral atoms on the metal.
M+ (aq) + e– → M(s)
The set-up involving the metal electrodes and the solution of their ions is called the metal ions/metal system , M+ (aq) /M(s) or a half cell.
Zinc ions/Zinc System:
If a zinc plate is dipped into a solution of
