Redox Equilibria of Iron in Acid Mine Waters... 

The chemical equilibria approach used in this study have enabled us to identify which parts of an acid mine drainage system are in equilibrium and which parts are not. Our results have provided greater insight into the chemical processes of acid mine waters in particular and the redox relations of iron in general. 

The last step in complexity that we will explore in detail for the construction of diagrams to illustrate redox equilibria involves the addition of heterogeneous equilibria to redox and acid-base equilibrium diagrams. We will illustrate this system with a ps-pH diagram for iron species in aqueous solution containing no anions other than hydroxide, We will expand on this diagram later in this chapter during the discussion of iron chemistry.
