Abstract
Conductivity measurements of solutions of sodium decyl sulfate and sodium dodecyl sulfate were made in water, N,N-dimethylformamide, and dimethyl sulf-oxide at 25 C. Within the concentration range 1 to 100 millimoles, the surfactants were found to form micellar aggregates. The critical micelle concentration values were found to depend on the dielectric constant of the medium and also on the hydrogen bonding nature of the solvent. The role of hydrogen bonding nature of the solvent in micelle formation is discussed.
