Abstract
Sodium, calcium, aluminum, and tin stearates behave as weak electrolyt es in dilute solutions (60% benzene + 40% methanol, vol/vol) below the critical micelle concentration, and conductance data can be explained on the basis of Ostwald's formula and the Debye-Huckel theory of weak electrolytes. Dissociation constants and thermodynamic parameters for dissociation and micellization of these soaps were also evaluated. Mi cellization was spontaneous and predominant over the dissociation proc ess.
