Electrochemical series

The standard electrode potential at 298K for various metal - metal ion electrodes are arranged in the decreasing order of their standard reduction potential values as shown in the figure.

Electrochemical series

We have already learnt that the standard single electrode potentials are measured using standard hydrogen electrode. The standard electrode potential at 298K for various metal - metal ion electrodes are arranged in the decreasing order of their standard reduction potential values as shown in the figure.


This series is called electrochemical series.

The standard reduction potential (Eº) is a measure of the oxidizing tendency of the species. The greater the Eº value, greater is the tendency shown by the species to accept electrons and undergo reduction. So higher the (Eº) Value, lesser is the tendency to undergo corrosion
