Experimental Data:   (Notes on the Nomenclature)
t/°CHenry's law constant [m**3 atm mol-1]102 * Mass Fraction w1 (compiler) 104 * Mole Fraction x1 (compiler)
24.855.32 x 10-40.35122.511
   The original method and apparatus for the determination of Henry's law constants, described by Mackay et al. (ref. 1), were used. The general procedure was to add an excess quantity of tribromomethane to distilled deionized water and mix the system overnight.  A portion of the solution was returned to the stripping vessel. Tribromomethane was stripped isothermally from the solution at a known gas flow rate. The Henry's law constant was calculated from the log of the concentration versus time plot. The experimental  data values are averages of two or more replicates.

Source and Purity of Materials:
   (1) Source not given. Purest quality available and was used without further purification, stated purity of > 99 %.
   (2) Distilled and deionized.

Estimated Errors:
   Solubility: ± 6 % std. dev.
   Temperature: ± 0.05 K.
