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 (2015) for further details.

Notes

6) Only the tabulated data between T = 273 K and T = 303 K from Dean (1992) were used to derive H and its temperature dependence. Above T = 303 K, the tabulated data could not be parameterized very well. The partial pressure of water vapor (needed to convert some Henry's law constants) was calculated using the formula given by Sander et al. (1995). The quantities A and α from Dean (1992) were assumed to be identical.
42) The value is incorrect. See erratum (Brimblecombe and Clegg 1989).
60)

H′ = 8.2×109×exp(10000 K ((1)/(T)−(1)/(T))) (mol2)/(m6 Pa) (see Errata!)

61)

H′ = 1.3×1010×exp(10000 K ((1)/(T)−(1)/(T))) (mol2)/(m6 Pa) (see Errata!)

62)

H′ = 7.0×109×exp(10000 K ((1)/(T)−(1)/(T))) (mol2)/(m6 Pa) (see Errata!)

63)

Chameides and Stelson (1992) give a value of H′ = 7.1×109×exp(6100 K ((1)/(T)−(1)/(T))) (mol2)/(m6 Pa). They refer to Jacob (1986) and Chameides (1984) as the source but this value cannot be found there. (see Errata!)
