Specific features of hydration of gaseous nitrogen and oxygen, revealed from data on their solubility in water H/D isotopomers

The H/D isotope effects in the thermodynamic functions of solvation of N-2 and O-2 were calculated from the experimental data on the solubility of these nonpolar gases in H2O and D2O at similar to 0.1 MPa and 278-318 K. ne sharp increase in the solubility in going from N-2 to O-2 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.
