Frequency Dispersion of the Electroelasticity Modulus in Aqueous Electrolyte Solutions

Abstract

Friction coefficients β_a and β_b, relaxation times τ_a, τ_b, τ_ab, and ∈(ω) for aqueous solutions of LiCl, NaCl, KCl, RbCl, CsCl are numerically calculated as functions of concentration c, density ρ, and temperature T in a wide range of frequencies ω using analytical expression for the electroelasticity modulus ∈(ω) obtained previously in the case of exponentially relaxing flows for a specific form of potential energy corresponding to the interaction between structural units of solution Φ_ab(r) and the equilibrium radial distribution function g_ab(r). The obtained theoretical data are presented in the form of tables and graphs and are shown to be in a satisfactory agreement with experimental results.
