The present investigation deals with the relative facets of alkali (Li, Na, K) and alkaline earth metal (Mg, Ca, Sr, Br) Myristates at different temperatures (30°-50°C). Thermodynamic parameters (change in enthalpy/free energy/entropy) for both dissociation and association processes have been used to look into the solution behaviour of these surfactants in 50% methanol +50% chloroform (V/V). Besides thermodynamic consideration, other parameters such as degree of dissociation, a and dissociation constant, KD etc are used to delve into the dissociation aspects of these systems. The data for critical micelle concentration, cmc are also reported and explained.

Abstract


The present investigation deals with the relative facets of alkali (Li, Na, K) and alkaline earth metal (Mg, Ca, Sr, Br) Myristates at different temperatures (30°-50°C). Thermodynamic parameters (change in enthalpy/free energy/entropy) for both dissociation and association processes have been used to look into the solution behaviour of these surfactants in 50% methanol +50% chloroform (V/V). Besides thermodynamic consideration, other parameters such as degree of dissociation, a and dissociation constant, KD etc are used to delve into the dissociation aspects of these systems. The data for critical micelle concentration, cmc are also reported and explained.
