 Experimental Data:   (Notes on the Nomenclature)
  
t/°CHenry's law constant [m**3 atm mol**-1]102 * Mass Fraction w1 (compiler) 103 * Mole Fraction x1 (compiler)
24.855.45 x 10-30.5611.026
 Method/Apparatus/Procedure:
   The original method and apparatus for the determination of Henry's law constants, as described by Mackay, et al.,1 was used. The general procedure was to add an excess quantity of 1,1-dichloroethane to  distilled deionized water, place a sample water bath thermostat, and mix overnight. A portion of this solution was returned to the stripping vessel. 1,1-Dichloroethane was stripped isothermally from the solution mixture at a known gas flow rate. The Henry's las 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) Purest quality available, used without further purification, stated purity greater than 99 %.
   (2) Distilled and deionized.

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