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_US High temperature chemistry Lanthanum compounds Cations Dissertations, Academic Thermodynamics of 3+ metal cation containing systems Thesis 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 URL http://localhost:4000/bitstreams/a8c8ff8d-a8e1-48dd-a7fd-b856e80d8467/download File MD5 4214a461690892790eaa16381e79c8e6 4177662 application/pdf MQ83761.pdf URL http://localhost:4000/bitstreams/bcf8b676-451a-4608-b174-57af6d46c3ed/download File MD5 28525e7037f77c09a89c05c619278686 201375 text/plain MQ83761.pdf.txt
