The potential vs pH diagram originated by Dr. Marcel Pourbaix and generally referred to as the Pourbaix Diagram, consolidates a vast amount of thermodynamic data into a relatively simple, concise graphical form. Pourbaix Diagrams are now available for all of the metallic species of the periodic table.1  While these diagrams are of considerable qualitative and quantitative usefulness, they have important limitations. For example, the equilibrium diagram does not contain kinetic information, and second, only pure metals have been studied until recently. The organizations forming the Center for Applied Thermodynamics and Corrosion (University of Florida and CEBELCOR) have pioneered the development of electrochemical techniques in combination with experimental potential vs pH diagrams.
