Abstract

Thermodynamics of micellar systems Part I : Apparent and partial molar volumes of sodium alkanoates according to the mass-action model (MAM)

Densities of the homologous sodium caboxylates were measured with a flow densimeter. Results were analysed according to the mass-action model. The first and some times the second micellar critical concentrations were determined. The apparent and partial molar volumes were calculated as well as the excess volumes. The solute-solute and solute solvent interactions were discussed.
