Vapor pressures of H2O(16) (ice and liquid), H2O(18) (ice and liquid), D2O(16) (ice and liquid), and of solutions of NaCl, KCl, LiCl, CsCl, NaI, NaBr, KF, CaCl2, and Na2SO4 (mostly from 0 to 100C, and over wide concentration ranges) in H2O and D2O were determined in a new high precision apparatus. The data was thoroughly analyzed thermodynamically and equations and tables presenting the isotope effects on the excess free energies, enthalpies and entropies of solution and on the osmotic coefficients and the activity coefficients are presented at temperatures between 0 and 100C, and to near saturation. The data are discussed in terms of models for aqueous solutions. (Author) |
