Stability Field Diagrams as Aids in Iron Chemistry Studies
Common iron‐bearing minerals of rocks and soils include oxides, carbonates, and sulfides. Under certain conditions, any of these may be attacked by water, and enough iron may thus go into solution to be troublesome to the water user. Iron oxides, for example, are dissolved by water at a nearly neutral pH below the water table if oxygen is almost entirely absent. Under these conditions iron carbonate may also be quite soluble. The sulfide minerals containing iron, of which pyrite is probably the most common, are relatively insoluble in alkaline‐reducing environments but can be dissolved easily when oxidizing conditions prevail. In the following discussion, these relationships will be considered quantitatively.
