Electrochemical series is based on:
Correct answer: B. Redox scale
- A. pH scale
- B. Redox scale
- C. Arrhenius scale
- D. Hydrogen scale
Explanation
The correct answer is the 'Redox scale.' The Electrochemical Series is a list of elements and ions sorted by their standard electrode potentials, indicating their tendency to be reduced or oxidized in redox reactions. This series helps predict the direction of electron flow in electrochemical cells. Other options like the pH scale, Arrhenius scale, and a non-existent 'Hydrogen scale' are unrelated to the redox-based principles that form the foundation of the Electrochemical Series.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
