The Gibbs adsorption isotherm for quaternary systems of water, weak base, HCl or NaOH, and NaCl including a vapor-solution interface is expressed in terms of variations of chemical potentials of neutral components added to make up the solution. Four systems are treated, and the Gibbs convention is introduced in such a way that the surface excess of added water is zero and the surface excesses of solute components are defined. Assuming that the activity coefficients of solute components are unity, the lowering of surface tension is given in terms of variations of total molar concentrations of weak base or its hydrochloride, HCl or NaOH, and NaCl, or of pH of the solution.
