Abstract Conductivities of (0.001–0.012) m sodium dodecyl sulfate have been determined in water and the presence 0.10 aqueous glycine/alanine/glycylglycine at 298.15, 303.15, 308.15, 313.15 K. From specific conductivity data, critical micellar concentration, degree counter ion association, counterion dissociation, free energy transfer hydrophobic chain from medium to interior micelle, surface contribution, standard micellization, enthalpy entropy micellization computed. The thermodynamic parameters effect additives on these used study interactions present systems.
