Herein, we employed the conductometric measurement technique for the estimation of the interaction between two oppositely charged surfactants (anionic, sodium dodecyl sulfate [SDS] and tetradecyltrimethylammonium bromide [TTAB]) in two chloride (NaCl/NH4Cl) salts in the range of temperatures from 298.15 to 318.15 K. The deviation of experimental critical micelle concentration (cmc) from the corresponding ideal values of cmc (cmcid), the values of interaction parameters (β), and activity coefficients (f1 and f2) of the components reveal the existence of the interaction amongst the investigated components. The attained cmc values for SDS/SDS + TTAB decline with the rise of temperature in H2O/electrolytes medium. The reduction of cmc in the presence of electrolytes reveals the facilitated micellization in the electrolyte medium. The assessed values of the micellar mole fraction of TTAB (X1) obtained from theoretical models signify the significant contribution of TTAB in SDS + TTAB mixed micellization. The estimated negative values of free energy (
ΔGmo) and excess free energy (ΔGex) of micellization reveal that micellization is spontaneous and mixed micelles are extra stable than distinct micelle, respectively. The enthalpy (
ΔHmo) and entropy (
ΔSmo) in addition transfer energies of micellization were also evaluated and explained thoroughly.
