Abstract:
The micellar behavior of the binary mixed systems of sodium n-hexylsulfate with sodium n-decyl-, n-dodecyl-, and n-tetradecylsulfate has been studied. The critical micelle concentration of the mixtures was quantitatively estimated by conductance methods. The micellar composition in the micelles was determined by the Motomura model and the mutual interactions were estimated from Holland and Rubingh's theory. The surfactant mixtures were found to be nonideal. The influence of the alkyl chain length in these parameters was studied. Copyright 2000 Academic Press.

Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules, atoms, and/or ions)...
