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

1)	A detailed temperature dependence with more than one parameter is available in the original publication. Here, only the temperature dependence at 298.15 K according to the van 't Hoff equation is presented.
21)	Several references are given in the list of Henry's law constants but not assigned to specific species.
101)	Lelieveld and Crutzen (1991) assume the temperature dependence to be the same as for a(H⁺)a(NO₃⁻)/p(HNO₃) in Schwartz and White (1981).
102)	H_s′ = 2.6×10⁷×exp(8700 K (1/T−1/T^⊖)) mol²/(m⁶ Pa)
103)	H_s′ = 2.4×10⁷×exp(8700 K (1/T−1/T^⊖)) mol²/(m⁶ Pa)
104)	Pandis and Seinfeld (1989) refer to Schwartz (1984) as the source, but it is probably from Schwartz and White (1981).
105)	The value is incorrect. See erratum by Brimblecombe and Clegg (1989).
