Data

The first column contains Henry's law solubility constant

H_{s}^{cp}

at the reference temperature of 298.15 K.
The second column contains the temperature dependence

d ln H_{s}^{cp} / d
(1/ T)

, also at the reference temperature.

Type

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 (2023) for further details.

Notes

21)	Several references are given in the list of Henry's law constants but not assigned to specific species.
216)	Petersen et al. (1998) give the invalid unit "mol L⁻¹ ppm⁻¹". Here, it is assumed that "ppm" is used as a synonym for "10⁻⁶ atm".
217)	Shon et al. (2005) refer to Petersen et al. (1998) as the source, but a different value is listed there.

The numbers of the notes are the same as in Sander (2023). References cited in the notes can be found here.
