Abstract:
Graphical stability relations in redox systems known as Pourbaix diagrams are analyzed employing the concept of overall stability of chemical species in multiple chemical reaction systems recently developed by us (Fishtik, I. J. Phys. Chem. B 2005, 109, 3851). The overall stability approach provides a simple and systematic algorithm for generating thermodynamically and stoichiometrically consistent Pourbaix diagrams that are referred to as overall Pourbaix diagrams. The conditions under which the conventional Pourbaix diagrams coincide with the overall Pourbaix diagrams are also discussed.

Consider the Fe3+/Fe2+ half-reaction, which has a standard-state potential of +0.771 V. At potentials more positive than +0.771 V, Fe3+ predominates, whereas Fe2+...
The Nernst Equation
The interconnection between standard cell potentials and various thermodynamic parameters such as the standard free energy change ΔG° and equilibrium constant K has been previously explored. For example, a redox reaction involving zinc(II) and tin(II) ions at 1 M concentration with Eºcell = +0.291 V and ΔG° = −56.2 kJ is spontaneous.
Cell Potential and Free Energy
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...
