 Experimental Data:   (Notes on the Nomenclature)
  
t/°CHenry's law constant [m**3 atm mol**-1]102 * Mass Fraction w1 (compiler) 105 * Mole Fraction x1 (compiler)
24.853.02 x 10-27.61 x 10-28.92
 Method/Apparatus/Procedure:
   The original method and apparatus for the determination of Henry's law constant, as described by Mackay et al. (ref. 1), was used. The general procedure was to add an excess quantity of tetrachloromethane to distilled deionized water, place the sample in a  thermostat bath, and provide overnight mixing. A portion of this solution was returned to the stripping vessel. Tetrachloromethane 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 was used without further purification. Stated purity > 99 %.
   (2) Distilled and deionized.

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