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

161)	Saiz-Lopez et al. (2014) refer to Saiz-Lopez et al. (2008) as the source, but the quoted value cannot be found there.
162)	It is unclear to which isomer the value of the Henry's law constant refers to.
163)	Assumed to be infinity by analogy with INO₃.

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