Abstract
The variation with pH of the surface potentials of spread monolayers of weak acids or bases may be used to calculate the intrinsic ionization constants of the film-forming molecules. The method is valid for condensed monolayers at the air/water interface for regions of a low degree of ionization only. The intrinsic constants for stearic acid and nonadecylamine monolayers are similar to the ionization constants for short-chain fatty acids and amines in aqueous solution. The relations between this and other methods of treating the ionization of a weak acid or base in a surface are discussed.
