Densities and viscosities of aqueous solutions of cesium trifluoroacetate have been measured at T ) (298.15, 303.15, 308.15, and 313.15) K and at atmospheric pressure. Apparent molar volume (ov), partial molar volume (oo v), and the ion ion interaction parameter (Sv) have been calculated from experimental values of densities. The calculated values for oo v are (105.522 * 10-6, 109.2591 * 10-6, 113.028 * 10-6, and 115.487 * 10-6) m3 * mol-1, and those of Sv are (-24.383 * 10-6, -33.229 * 10-6, -42.194 * 10-6, and -49.046 * 10-6) m3 * mol-3/2 * kg-1/2 at T ) (298.15, 303.15, 308.15, and 313.15) K, respectively. The viscosity data have been analyzed with the Jones-Dole equation. At T ) (298.15, 303.15, 308.15, and 313.15) K, the calculated values for the Jones-Dole coefficient (B) are (0.1534, 0.1612, 0.1725, and 0.1829) kg * mol-1, and those of intercept (A) are (-0.0223, -0.01691, -0.01360, and -0.01120) mol * kg-1/2, respectively. The molality range has been studied between (0.05671 and 0.5671) mol * kg-1. The parameters calculated from experimental values of densities and viscosities indicate strong solute-solvent interactions and water structuring.
