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.


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.
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.
81) Value at T = 288 K.
215) Temperature dependence calculated using linear free energy relationships (LFERs).
216) Petersen et al. (1998) give the invalid unit "mol L−1 ppm−1". Here, it is assumed that "ppm" is used as a synonym for "10−6 atm".
