dc.description.abstract Measurements of relative densities and relative massic heat capacities have been made for several aqueous rare earth chloride and perchlorate systems. Densities and relative massic heat capacities of acidified aqueous perchlorates of yttrium, ytterbium, dysprosium, and samarium as well as the chlorides of yttrium, ytterbium, dysprosium, samarium and gadolinium have been measured at the temperatures 288.15, 298.15, 313.5 and 328.15 K. Using the density and massic heat capacity data, apparent molar volumes and apparent molar heat capacities have been calculated. These data have been modeled using the Pitzer ion interaction approach as well as the Helgeson, Kirkham and Flowers equations of state. Apparent molar volumes and apparent molar heat capacities previously presented in the literature have been compared to the data presented here. single ion apparent molar volume and apparent molar heat capacity contributions were calculated. Infinite dilution properties have been compared to existing models used to predict infinite dilution properties. Densities of aqueous perchloric acid and ytterbium perchlorate at the temperatures from 348.15 to 423.15 K and at pressured from 10.00 to 30.00 MPa were measured. Apparante molar volumes were calculated from the density measurements. The apparent molar volume data were modeled using Pitzer ion interaction theory as well as HKF equations of state. Models presented are compared to existing models. en
