Numerically Calculating the Concentration and Temperature Dependences of the Electrical Conductivity of Aqueous Electrolyte Solutions

Kinetic equations are used to find analytical expressions for dynamic electrical conductivity and electroelasticity modulus under conditions where relaxing currents attenuate according to an exponential law. Along with the molecular parameters, the coefficients in the integrands contain potential energy of interaction and radial distribution function . Isofrequency electrical conductivities of aqueous solutions of LiCl, NaCl, KCl, and CsCl electrolytes are calculated numerically for a model solution. Explicit expressions for and are found, along with the corresponding values of concentration С and temperature Т . The results from numerical calculations are in satisfactory agreement with experimental findings.
