H. Topallar et Y. Bayrak, Thermodynamics of the dissociation of chromium soap solutions in benzene-dimethyl formamide, TURK J CHEM, 23(1), 1999, pp. 31-39
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.
