Pourbaix diagram of iron. [1] The Y axis corresponds to voltage potential. In electrochemistry, and more generally in solution chemistry, a Pourbaix diagram, also known as a potential/pH diagram, E H –pH diagram or a pE/pH diagram, is a plot of possible thermodynamically stable phases (i.e., at chemical equilibrium) of an aqueous electrochemical system.

Marcel Pourbaix (16 September 1904 – 28 September 1998) was a Belgian chemist and pianist. [citation needed] He performed his most well known research at the University of Brussels, studying corrosion. [1] His biggest achievement is the derivation of potential-pH, better known as “Pourbaix Diagrams”.
Pourbaix diagram for water, including stability regions for water, oxygen and hydrogen at standard temperature and pressure (STP). The vertical scale (ordinate) is the electrode potential relative to a SHE electrode. The horizontal scale (abscissa) is the pH of the electrolyte (otherwise non-interacting). Above the top line oxygen will bubble ...
It has a 50-ounce water reservoir on the back, for numerous refills and added convenience. "As an ex-Dunkin [Donuts] employee and current Starbucks fanatic, I'm a big espresso girl," shared one ...

The water in the pores of Portland cement concrete is normally alkaline with a pH in the range of 12.5 to 13.5. This highly alkaline environment is one in which the steel rebar is passivated and is protected from corrosion. According to the Pourbaix diagram for iron, the metal is passive when the pH is above 9.5. [1]
