Theelectrochemical series, also known as theactivity series, is a list of metals listed in order of decreasing reactivity or in order of decreasing ease of oxidation. The metals at the top of the series, such as the alkali metals and the alkaline earth metals, are more reactive or are most easily oxidized than the metals found at the bottom of the series. This basically means that they can react more easily to form compounds. These metals at the top of the activity series are calledactive metals.

application of electrocheemical series

A series in which the reduction electrode potentials of various electrodes have been arranged in the increasing order (downwards) is called Electrochemical Series .

The standard reduction potential of hydrogen is zero.The electrodes above hydrogen have negative reduction potential while those place below it have positive reduction potential and vice-versa.

To understand the importance and application of Electrochemical series we have to study about Oxidation,Reduction and Standard Reduction Potential.
