Equilibrium Potentials of Reactions with Iron at

In addition to the reaetions a) and b) we have also other reaetions of importanee for iron in water  

The equilibrium potentials of these reactions are determined in the same way as for the reactions a) and b). Note that is involved in all reactions b)-f). Therefore, equilibrium potentials vary linearly with pH, as shown for reaction b).
