Abstract

The conductometric studies of the solution of manganese butyrate and caprylate in a mixture of 50% Benzene and 50% Methanol (v/v) were employed to determine the specific conductance, limiting molar conductance at infinite dilution, degree of dissociation, dissociation constant and CMC. The values of critical micelles concentration decreases with increasing chain length of fatty acid component. The result show that the soaps behaves as a weak electrolytes below the CMC. The thermodynamic parameters for both dissociation and association processes are evaluated.
