It is often helpful to review Pourbaix diagrams in order to predict some of the side reactions. In his 1945 doctoral thesis, Marcel Pourbaix (1904-1998) examined the relationships between electrochemical potential and pH, correlating them in a two-dimensional plot called a predominance diagram (later also called a Pourbaix diagram). In 1966 the Centre Beige d Etude de la Corrison (CEBELCOR), with the help of many other contributors, compiled thermodynamic and structural data for virtually the entire periodic table in the Atlas of Electrochemical Equilibria in Aqueous Solutions.

Within the field between the upper and lower limits H O dipole is stable. However, this moisture stability has a tentative nature. The upper stability limit of H O molecule corresponds with oxygen partial pressure of 1 atm and hydrogen, 10 atm, and the lower - hydrogen partial pressure of 1 atm and oxygen, 10 atm. Marcel Pourbaix (1904-1998) showed that from the position of redox reactions the state of H O may be considered most stable when partial pressure is half of H partial pressure. Moisture... 

Thermodynamic calculations are extremely important in the field of corrosion because they can be used to predict the tendency for a metal to corrode in a given environment. Details of thermodynamic principles can be found in a number of textbooks [1-3]. The Atlas of Electrochemical Equilibria in Aqueous Solutions by Marcel Pourbaix provides a comprehensive summary of the application of thermodynamics to corrosion as well as a compendium of stability diagrams for all elements in water [4). 

It is possible to use the Nernst equation, which relates reversible potential to pH and cation concentration, to generate phase stability plots in potential/pH space. Such diagrams are called Pourbaix diagrams, after Marcel Pourbaix who pioneered their development. Pourbaix diagrams are visual representations of the equilibrium conditions in potential/pH space. They are based on thermodynamics, and indicate the stable phase for given conditions, but say nothing about rates of reactions from one phase to another. 

The above quotation from Georges Urbain has been reprinted from a book written by the corrosion scientist who more than any other person has contributed to the thermodynamic basis for modem corrosion science and technology, namely the Belgian professor Marcel Pourbaix (1904—1998) [3.1]. 

The Pourbaix diagrams (also known as potential-pH (Eh-pH) diagrams since this is the simplest representation proposed by Marcel Pourbaix) are the more famous PZD in electrochemistry. There are many papers in the scientific literature that describe their construction algorithms (Fig. 1).

Marcel Pourbaix (1904-1998) was a Belgian physical chemist who is known for inventing the (electric) potential-pH, better known as Pourbaix, diagrams in the 1930s. In 1963, Pourbaix produced the Atlas of Electrochemical Equilibria, which contained potential-pH diagrams for all elements known at that time.

The hydrogen ion concentration - expressed by pH - is an important parameter for calculating electrochemical equilibrium potentials. The Pourbaix diagram maps in a clear way the influence of the pH value on complicated electrochemical equilibria. The diagram form, which is named after the Belgian corrosion researcher Marcel Pourbaix, was developed in the 1940s.
