Table entries are sorted according to reliability of the data, listing the most reliable type first: L) literature review, M) measured, V) VP/AS = vapor pressure/aqueous solubility, R) recalculation, T) thermodynamical calculation, X) original paper not available, C) citation, Q) QSPR, E) estimate, ?) unknown, W) wrong. See Section 3.1 of Sander (2015) for further details.


7) Several references are given in the list of Henry's law constants but not assigned to specific species.
19) Value at T = 310 K.
89) Measured at high temperature and extrapolated to T = 298.15 K.
92) Yaws and Yang (1992) give several references for the Henry's law constants but don't assign them to specific species.
100) Calculated from the solvation enthalpy, using the van 't Hoff equation.
103) The value is most probably taken from the report by Howe et al. (1987).
116) Value given here as quoted by Staudinger and Roberts (1996).
121) Sieg et al. (2009) also provide data for supercooled water. Here, only data above 0 °C were used to calculate the temperature dependence.
123) It was found that Hs changes with the concentration of the solution.
126) Value at T = 296 K.
129) Calculated using Gh and Hh from Table 2 in Andon et al. (1954). Note that the thermodynamic functions in that table are not based on their α in Table 1. Instead, the expression exp(−Gh/(RT)) yields the Henry's law constant Hsxp in the unit 1/atm.
130) Values for salt solutions are also available from this reference.
138) Different types of Henry's law constants of Ryu and Park (1999) are inconsistent, with 14 % difference.
