Negative potential of the oxidation of iron(II) to iron(III)

aqueous solutions of iron(II) salts do not spontaneously reduce aqueous protons to hydrogen gas. If you mix iron(II) sulfate with water, for example, hydrogen bubbles do not spontaneously form. Hydrogen gas releases more energy when burned in oxygen than iron(II) salts do when they react with oxygen.

Redox Conditions in Contaminated Ground Water

If nitrate concentrations exceed about 0.5 mg/L in anaerobic ground water, then nitrate reduction is likely. If anaerobic ground water lacks nitrate, and if reduced manganese (Mn(II)) or iron (Fe(II)) concentrations increase along a ground-water flow path, then manganese or iron reduction is indicated.
