| Abstract: | A titrimetric determination of some sulphonamides with 0.1 M sodium hydroxide in the presence of hexadecylpyridinium chloride is described. Potentiometric titrations are slow; visual titrations are satisfactory. The pKa shift can be interpreted in the light of general micellar behaviour. |
