Critical micelle-formation concentrations and Kraft points of sodium
monoalkyl sulfosuccinates homologues from C10 to C14 are determined by conductometry.
Degrees of counter-ion binding by micelles are calculated by the
Evans’ method, and then values of the Gibbs free energy of micelle formation
are found. Magnitudes of counter-ion-binding degrees and values of the
Gibbs free energy are higher than those are for surfactants with singly
charged anions of the same hydrocarbon-radical length.
