Standard Electrode Potentials Hyperphysics Concepts

standard electrode potentials. In an electrochemical cell, an electric potential is created between two dissimilar metals. this potential is a measure of the energy per unit charge which is available from the oxidationreduction reactions to drive the reaction.
