The present work is concerned with experimental results of conductometric properties of Biopolymer of chitosan solutions in HCl acid and dimethyl sulphoxide DMSO. The electrical conductivity of solutions of Chitosan CH + DMSO/HCl over a wide range of concentrations and at different temperatures was measured. The reduced electrical conductivity and the activation energy of reduced electrical conductivityare calculated. Biopolymers solutions exhibit a critical concentration c*, separating dilute solutions into dilute solutions and semi dilute solutions. The most important results refer to the activation energy of reduced electrical conductivity found from Arrhenius plots. The dependence of the activation energy on solution concentration and temperature is discussed. The biopolymer CH behaviour can be extrapolated from the Flory-Huggins theory by decomposing such as. The dilute solution behaviour of Arrhenius is described by the CH-DMSO/HCL interaction and represented by the function. For the semi – dilute solution behaviour of non-Arrhenius which is described by the interaction between the CH-CH and DMSO/HCL-DMSO/HCL and represented by the function.
