The electrical conductance of the systems Water-0.2N sodium salts of fatty acids (sodium caprylate and caprate) and Butanol-I at different concentrations of Butanol-I has been studied. The effect of free acid has also been studied with a view to determine its effect on the behaviour of these systems. It has been concluded that two types of micelles are formed in such systems. Up to 50% Butanol-I concentration hydrophilic oleomicelles exist and above 50% Butanol-I concentration lipophilic hydromicelles are formed. It has also been observed that the conductivity of the solutions decreases with the increase in Butanol-I concentration as well as with the increase in the chain length of the soap. The results are in aggreement with viscosity and surface tension results of these systems.
