| 英文摘要 | Isobaric heat capacities of aqueous solutions of Li2SO4, LiClO4, and LiCF3SO3 have been measured at 298.15 K and 0.1 MPa up to high concentrations using a Picker flow calorimeter. Apparent molar isobaric heat capacities, C-p,C-phi, derived from these data were fitted within the limits of experimental precision with an extended Redlich-Rosenfeld-Meyer type of equation, which was also used to estimate the standard state (infinite dilution) quantities,. C-p,phi(o), for eadh salt. The latter values were combined with appropriate literature data to produce a robust estimate of C-p,phi(o) (Li+(aq)) = -3 +/- 2 J.K-1.mol(-1). Where comptison was possible, C-p,C-phi(LinX) values were closely parallel to those of the corresponding acids over the whole concentration range, even when the shapes of the curves were highly unusual. In contrast, C-p,C-phi(NanX) values always exhibited a crossover with the lithium salt data at a concentration of about 1 mol.kg(-1), which appears to reflect differences in the hydration of the two cations. |
