Pourbaix diagram of Iron

In chemistry, a Pourbaix diagram, also known as a potential/pH diagram, maps out possible stable (equilibrium) phases of an aqueous electrochemical system. 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.

The diagrams are named after Marcel Pourbaix (19041998), the Russian-born chemist who invented them.
