Relative densities of HCF3SO3(aq) at molalities 0.12 < m/(mol-kg-1) < 2.1 were determined at temperatures from 283 K to 328 K at 0.1 MPa. Apparent molar volumes calculated from the measured densities were represented by the Pitzer ion-interaction treatment. The temperature and pressure dependence of the standard partial molar volume and the second virial coefficients in the Pitzer equation were expressed by empirical expressions in which the compression coefficient of water and temperature were used as independent variables. The conventional standard partial molar volumes V‡(CF3SO 3 - , aq) fromT = 283 K to 573 K were calculated from the experimental values for V‡(NaCF3SO3, aq) and known values for V‡(Na+, aq). The values of V‡(CF3SO3/-, aq) at temperatures from 283 K to 328 K obtained from the values of V‡(NaCF3SO3, aq) and V‡(HCF3SO3, aq) agree to within 1.2 cm3-mol-1.
