ABSTRACT

The densities and viscosities of ammonium acetate, potassium acetate, sodium acetate, and lithium acetate have been measured in 10, 20, and 30 mass % of tetrahydrofuran + methanol binary solvent mixtures at (303.15, 313.15, and 323.15) K. Apparent molar volumes (Vae), partial molar expansibility (E2), viscosity B-coefficients, and free energy of activation for viscous flow (centsi0*) are obtained from these data. The limiting apparent molar volumes (Vae0) and experimental slopes (SV / ) derived from the Masson equation have been interpreted in terms ofion-solvent and ion-ion interactions, respectively. The viscosity data have been analyzed using the Jones-Dole equation, and the derived parameters B and A have also been interpreted in terms of ion-solvent and ion-ion interactions. The sound speeds measured at 303.15 K have been used to study the apparent molal isentropic compressibility (KS,ae), intermolecular free length (Lf), relative association (RA), relaxation strength (rcents), and specific acoustic impedance (Z) of the solutions.
