ABSTRACT

Data for the conductivity (at 298.15 K), density and viscosity (both at 278.15, 288.15, 298.15, 308.15, & 318.15 K) of aqueous solutions of choline chloride (ChCl) and chlorocholine chloride (Cl-ChCl) are reported for solute molalities m . 2.0 mol kg-1 (ChCl), respectively . 2.1 mol kg-1 (Cl-ChCl). From the densities apparent molar volumes were calculated and the limiting partial molar volumes and Hepler s constants of ChCl(aq) and Cl-ChCl(aq) were evaluated. From the viscosities Arrhenius activation energies of viscous flow were determined
