When you are in need to learn about pourbaix diagrams, look no further than this collection of 101 Diagrams page. With a total of 5 diagrams, have a quick learn at the examples of pourbaix diagram. We’ll start by giving you the pourbaix diagram of Cu below.
Pourbaix Diagrams is also known as a potential/pH diagram, equilibrium diagram, EH-pH diagram, a pE/pH diagram on an E-pH diagram. As noted above, these diagrams are essentially phase diagrams that plot the map the conditions of potential and pH (most typically in aqueous solutions) where different redox species are stable. More examples of pourbaix diagrams are shown in the following images.
This diagram is used to show the directions of the various reactions at given pH and potential; to make a basis for estimation of the corrosion product compositions at various pH and potential combinations; and to show which environmental pH and potential changes will reduce or prevent corrosion. The lines in the Pourbaix diagram show the equilibrium conditions, that is, where the activities are equal, for the species on each side of that line. On either side of the line, one form of the species will instead be said to be predominant.
