⚠️ The Nernst equation relies on reactant and product activities rather than simple concentrations or partial pressures. In solutions with high ionic strength, activity coefficients deviate significantly from 1.0, requiring extended Debye-Hückel corrections for precise electromotive force (EMF) measurements.
