摘要：
The freezing point of mixtures of H 2 16O with H 2 17O was measured as a function of the molal concentration. The freezing points rose linearly with increasing molal concentration above that of pure ordinary water, H 2 16O, at 273.15 K. This confirms Kiyosawa's previous conclusion [K. Kiyosawa, J. Solution Chem. 20, 583 (1991).], drawn from findings on changes in the freezing point of mixtures of H 2 16O with H 2 18O or D 2 16O that even a difference in the number of neutrons in the hydrogen or oxygen atoms of water molecules makes them behave as different entities with respect to the colligative properties of solutions. This has been confirmed to also occur in mixtures of H 2 16O with H 2 17O.
