| Popis: | The freezing points of mixtures of benzene, C6H6, with one of its isotopes, C6D6 and 13C6H6, and those of acetic acid CH3COOH with its isotopes, CH3COOD and CD3COOD, were measured as functions of the molal concentrations of C6D6 and 13C6H6, CH3COOD and CD3COOD, respectively. They changed linearly or non-linearly with increasing molal concentration of C6D6 and 13C6H6, CH3COOD, and CD3COOD, respectively. These findings confirm Kiyosawa’s previous conclusion drawn from experiments on the freezing points of mixtures of H216O with H218O or H217O. This hypothesis states that even a difference in the number of neutrons in the hydrogen or oxygen atoms of water molecules makes water molecules behave as different entities with respect to the colligative properties of solutions. This concept can be extended to mixtures of ordinary benzene with either of its isotopes, C6D6 or 13C6H6, and those of ordinary acetic acid CH3COOH with either of its isotopes, CH3COOD or CD3COOD. |
