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

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.
23) The partial pressure of water vapor (needed to convert some Henry's law constants) was calculated using the formula given by Buck (1981). The quantities A and α from Dean & Lange (1999) were assumed to be identical.
81) Value at T = 288 K.
118) The value of ∆H° listed in Table 2 of Bartlett & Margerum (1999) is incorrect. The correct value can be found in the text on page 3411.
143) Dubik et al. (1987) measured the solubility in concentrated salt solutions (natural brines).
144) Value given here as quoted by McCoy et al. (1990).
145) The data from Dean & Lange (1999) were fitted to the three-parameter equation: Hscp= exp( −148.75647 +9709.80909/T +19.53408 ln(T)) mol m−3 Pa−1, with T in K.
