The enthalpy change for dissolving sodium dodecyl sulfate (SDS) crystals into aqueous solutions was measured as functions of temperature, sodium chloride concentration, and SDS concentration. From these calorimetric measurements, the partial molar enthalpy and heat capacity of SDS was determined in the monomeric and micellar states. Also, the enthalpy and heat capacity changes associated with micelle formation and the sphere- to-rod transition were determined. The findings are in agreement with previous estimates derived from quasielastic light scattering studies of micellar growth, and provide new information about the role of interfacial hydration and electrostatic factors in modulation of the sphere-to-rod transition. 54 references.
