WebbBecause the half reactions have different pH dependencies, a common approach is to compare the various half reactions by calculating the equilibrium constant at pH = 7. This constant is called p (w). For example, consider the SO4/HS half reaction: 1/8 SO4 2-+ 9/8 H+ + e- = 1/8 HS-+ 1/2 H 2O p = 4.25 we can write: pE = p - log (HS-)1/8 / (SO 4 http://thiele.ruc.dk/kemikurser/InorgChem/Noter/EpHe.pdf
