What is Electrochemical Series?
Also known as the activity series or electromotive series, this is a list of elements arranged in order of their standard electrode potentials. It predicts the direction of redox reactions and the relative ability of metals to be oxidized or reduced.

Frequently Asked Questions
Also known as the activity series or electromotive series, this is a list of elements arranged in order of their standard electrode potentials. It predicts the direction of redox reactions and the relative ability of metals to be oxidized or reduced.
The electrochemical series is used to predict the direction of redox reactions, the spontaneity of galvanic cells (positive E°_cell = spontaneous), the relative reactivity of metals, and to select appropriate electrode materials. It guides cathodic protection material selection and battery design.
Metals high in the series (Na, K, Ca) react violently with water, generating H₂ and heat — extreme fire and explosion hazard. The electrochemical series helps predict unexpected redox hazards when mixing solutions containing different oxidation state species.
The formula or notation for Electrochemical Series is: Arranged by E° (standard reduction potential); SHE: E° = 0.00 V
