| Abstract: | The H/D isotope effects in the thermodynamic functions of solvation of N2 and O2 were calculated from the experimental data on the solubility of these nonpolar gases in H2O and D2O at ～0.1 MPa and 278–318 K. The sharp increase in the solubility in going from N2 to O2 is caused both by a decrease in the contribution of the hydrophobic hydration and by the possibility of formation of H-type bonds by oxygen molecules with the aqueous environment. |
