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.


1) Vapor pressure data for water from Wagner and Pruss (1993) was needed to calculate H.
3) Value given here as quoted by Fogg and Sangster (2003).
5) Value given here as quoted by Lide and Frederikse (1995).
6) Only the tabulated data between T = 273 K and T = 303 K from Dean (1992) were used to derive H and its temperature dependence. Above T = 303 K, the tabulated data could not be parameterized very well. The partial pressure of water vapor (needed to convert some Henry's law constants) was calculated using the formula given by Sander et al. (1995). The quantities A and α from Dean (1992) were assumed to be identical.
92) Yaws and Yang (1992) give several references for the Henry's law constants but don't assign them to specific species.
148) Solubility in sea water at 20.99 % chlorinity.
149) Erratum for page 260 of Fogg and Sangster (2003): The corresponding equation in preferred units is incorrect. The last term must be divided by 10000 (i.e. 0.0704, not 704.
