Diagrama de Pourbaix
Predominant ion boundaries are represented by lines. As such a Pourbaix diagram can be read much like a standard phase diagram with a different set of axes. Similarly to phase diagrams, they do not allow for reaction rate or kinetic effects. Beside potential and pH, the equilibrium concentrations are also dependent upon, e. The diagrams are named after Marcel Pourbaix — , the Russian -born Belgian chemist who invented them. Pourbaix diagrams are also known as E H -pH diagrams due to the labeling of the two axes.
