Traube’s Rule for Soluble Monolayers of Homologous Strong Electrolytes

Abstract

By using the free energy of the adsorption of the CH₂ or the CF₂ group from water to the surface, W, and the surface potential of Gouy’s theory, Traube’s factor, K, that is, the ratio of the respective concentrations, C_n and C_n+1, required to effect the equal lowering of surface or interfacial tension for successive homologous strong electrolytes with n and n+1 CH₂ or CF₂ groups, has been derived as;
