The physicochemical properties of Dodecyltrimethylammonium Bromide (DTAB) and Sodium Dodecylsulfate (SDS) rich surfactants in aqueous medium have been studied by surface tension, viscosity, density, and sound velocity at T = 293.15, 298.15, and 303.15 K. The DTAB concentration varies from 0.0001 to 0.03 mol · L −1 in the presence of ≈0.01 mol · L −1 SDS and the SDS concentration varies from 0.001 to 0.015 mol · L −1 in the presence of ≈0.005 mol · L −1 DTAB, so that the concentrations of cationic (DTAB‐rich) and anionic (SDS‐rich) solutions are taken in the ratio of 3:1. The density ( ρ ) and sound velocity ( μ ) data are used for calculating apparent molar volume ( V ϕ ), friccohesity ( σ ), isentropic compressibility ( K s,ϕ ), surface tension ( γ ), and viscosity ( η ). These parameters reveals that the relative solute‐solvent and solute‐solute interactions of SDS‐DTAB and DTAB‐SDS in an aqueous medium with the help of physicochemical properties (PCPs).
