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

11)	Measured at high temperature and extrapolated to T^⊖ = 298.15 K.
12)	Value at T = 293 K.
21)	Several references are given in the list of Henry's law constants but not assigned to specific species.
218)	Value at T = 333 K.
219)	Calculated using linear free energy relationships (LFERs).
220)	More than one reference is given as the source of this value.
