Abstract

The solubility of argon was measured in D₂O (99.7%) at five temperatures: 5°, 10°, 15°, 20°, 25°C. The standard entropies, enthalpies, and free energies of solution were calculated, and compared with the corresponding values in H₂O. The differences in the thermodynamic functions of solution in D₂O and in H₂O are interpreted in terms of the "two-structure" model for liquid water, and are attributed to the difference in the "degree of crystallinity" of the two solvents.
