Abstract
Critical micelle concentrations and dissociation constants for chromium soa ps (myristate, palmitate and stearate) in a mixture of benzene and dimethyl formamide (7:3, vol/vol) were determined by means of conductivity measurem ents. These soaps behave as simple moderate electrolytes in dilute solution s. Critical micelle concentrations and dissociation constants decreased wit h increasing numbers of carbon atoms in the soap molecules. Thermodynamic p arameters such as heat of dissociation, Delta H-d, change in free energy, D elta G(d), and entropy, Delta S-d, per mole for the dissociation process we re also evaluated.
