Abstract
The autoprotolysis constant of water is shown to be unaffected by the presence of 0.05 M hexadecylpyridinium chloride (HPC) and an organic phase (dichloromethane). In the presence of 0.05 M sodium dodecyl sulphate (SDS), however, the pH scale is shortened by about 0.2 units because of the formation and solubilization of dodecyl sulphuric acid. Constants for the distribution of some amines (lidocaine, prilocaine and tocainide) between an aqueous phase and a micellar phase of HPC are reported, as is the equilibrium constant for the extraction of the lidocaine/dodecyl sulphate ion pair into a micellar phase of SDS.
