説明

Summary Potentiometric titrations of the anionic surfactant, sodium tetraphenylborate, with the cationic surfactants, tetradecyldimethylbenzylammonium chloride and cetylpyridinium chloride have been carried out. An S-shaped titration curve was obtained with a mercury indicator electrode referred to SCE. The potential change is considered to be due to change in the Lippmann potential of zero-charge when the solution is deaerated. When the solution is not deaerated, however, the potential change is considered to follow the zero-current potential. Sodium dodecylbenzenesulphonate can be accurately titrated with tetradecyldimethylbenzylammonium chloride potentiometrically.
