Characteristics of Electrochemical Series
Key characteristics of Electrochemical Series are:
- The substances that are stronger reducing agents than hydrogen are placed above hydrogen in the series and have negative values of standard reduction potentials.
- All those substances that have positive values of reduction potentials and placed below hydrogen in the series are weaker reducing agents than hydrogen.
- The substances which are stronger oxidizing agents than H+ ions are placed below hydrogen in the series.
- The metals on the top (having high negative values of standard reduction potentials) tend to lose electrons readily. These are active metals.
- The non-metals on the bottom (having high positive values of standard reduction potentials), tend to accept electrons readily. These are active non-metals.

Electrochemical Series
Electrochemical Series or Reactivity Series, is a list of metals and semi-metals ranked in order of their standard electrode potential or standard reduction potential. In the electrochemical series, metals and other substances are arranged in decreasing order of their tendency to gain electrons (reduce) or lose electrons (oxidize). Electrochemical Series is based on the measurements of the potential of various electrodes in comparison to the standard hydrogen electrode (SHE).
In this article, we will discuss the concept of the Electrochemical Series in detail including its definition, chart, as well as tricks to remember the Electrochemical Series.
