Özet:

 

Critical micelle concentrations and dissociation constants  for chromium soaps (myristate, palmitate and stearate) in a mixture of  benzene and dimethyl formamide (7:3, vol/vol) were determined by means  of conductivity measurements.  These soaps behave as simple moderate  electrolytes in dilute solutions.  Critical micelle concentrations and  dissociation constants decreased with increasing numbers of carbon  atoms in the soap molecules.  Thermodynamic parameters such as heat of  dissociation, DHd, change in free energy, DGd, and  entropy, DSd, per mole for the dissociation process were also  evaluated.
