Pourbaix diagrams are commonly given at room temperature, atmospheric pressure, and molar concentrations of 10 −6 and changing any of these parameters will yield a different diagram. The diagrams are named after Marcel Pourbaix (1904–1998), the Russian-born Belgian chemist who invented them. See more In electrochemistry, and more generally in solution chemistry, a Pourbaix diagram, also known as a potential/pH diagram, EH–pH diagram or a pE/pH diagram, is a plot of possible thermodynamically stable phases (i.e., at See more The vertical axis is labeled EH for the voltage potential with respect to the standard hydrogen electrode (SHE) as calculated by the Nernst equation. The "H" stands for hydrogen, although other standards may be used, and they are for room temperature … See more Even though Pourbaix diagrams are useful for a metal corrosion potential estimation they have, however, some important limitations: 1. Equilibrium is always assumed, though in practice it may differ. 2. The diagram does not provide … See more Pourbaix diagrams are also known as EH-pH diagrams due to the labeling of the two axes.
