What do you understand by electrochemical series?

What is an electrochemical series?

Answer 1

1. The electrochemical series is a list of elements or ions arranged in order of their standard electrode potentials, measured under standard conditions with respect to the standard hydrogen electrode.
2. It helps in predicting the oxidising and reducing strength of substances.
3. Elements at the top of the series have high positive potentials and act as strong oxidising agents, while those at the bottom have high negative potentials and act as strong reducing agents.
4. The series is useful in determining the feasibility and direction of redox reactions and helps in designing electrochemical cells.
