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

38)	Value at T = 303 K.
67)	There is a typo in Sander et al. (2011): the value for A should be −10.19 not 10.19.
68)	Modarresi et al. (2007) use different descriptors for their calculations. They conclude that a genetic algorithm/radial basis function network (GA/RBFN) is the best QSPR model. Only these results are shown here.
69)	Incorrect data are given by Burkholder et al. (2019) for HN₃. The correct parameter for the temperature dependence is A = −10.19 (Robert E. Huie, personal communication, 2021).
70)	Incorrect data are given by Burkholder et al. (2015) for HN₃. The correct parameter for the temperature dependence is A = −10.19 (Robert E. Huie, personal communication, 2021).
