Redox Equilibria in Natural Waters
Redox Equilibria in Natural Waters
Description:
This 28-page resouce, intended for a college-level introductory chemistry course, deals with the redox state of the aquatic environment and its relation to the geobiochemistry of some of the major elements. It begins with a review of the fundamental ideas of oxidation and reduction and electrochemical potentials and a discussion of electron activity, the electron free energy scale, and pE. Main topics covered include: electron transfer and and the oxidation state; latimer diagrams; the Nernst equation; electron activity and pE; redox equilibrium and pE; pE in water and natural aquatic systems; oxidizing-reducing capacity; pE diagrams and pH diagrams; redox reactions with nitrogen, sulfur, iron, manganese, and carbon in the aquatic environment; and oxidation and evolution. A list of references is included at the end of this resource.
