met and Eh = Eo, which is the intersection of the line with the vertical axis in Eh-pH plots. At the other extreme of reducing conditions in aqueous systems, hydrogen ion reduction to hydrogen gas is the lower stability of the system. how to build a database from scratch Eh-pH diagrams can now be generated by computer, but having students generate one by hand (Cu-Cl-H2O is a good example) makes the principles easier to understand, if time is available.

  • The reduction potential depends on the pH of the solution, so the Latimer diagram for chlorine in basic solution is different to that in acidic solution: the potentials are different, but also the actual species present in solution may change.
  • At last geochemists are offered one comprehensive reference book which gives the Eh-pH diagrams for 75 elements found in the earth's surface environment, …
  • The diagrams are named after Marcel Pourbaix (1904–1998), the Russian-born chemist who invented them. In sedimentary environments the concept of geochemical facies is best illustrated on an Eh-pH diagram, a diagram delineating the stability field of certain minerals in terms of the proton concentration (pH) and electron concentration (Eh).
