Chemical cells

This page covers the following topics:

1. Electrochemical series

Electrochemical series is a list of half equations and their corresponding electrode potentials. Standard electrode potential is the voltage that is created when a specific reduction or oxidation is occurring in comparison to hydrogen oxidation. The aforementioned potentials are usually measured for 1.00 mol/dmยณ ion solutions at standard room temperature and pressure. The greater the electrode potential, the more favourable a particular redox process is and the stronger oxidising agent the initial reactant is.

What is the relationship between the standard electrode potential and the reducing ability of a reactant involved in a corresponding equation?

The greater the electrode potential, the more favourable a particular redox process is and the stronger oxidising agent the initial reactant is. Thus, the greater the potential, the weaker the reducing ability of the reactant.

The greater the potential, the weaker the reducing ability.
