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.


59) Dubik et al. (1987) measured the solubility in concentrated salt solutions (natural brines).
66) Value at T = 275 K.
67) Value at T = 290 K.
68) Calculated using data from Wagman et al. (1982) and the aqueous-phase equilibrium Cl2 + Br2 ↔ 2 BrCl from Wang et al. (1994).
