Glass Ball as Bullet Solubility System: Trichloromethane (chloroform) with Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Trichloromethane (chloroform); CHCl3; [67-66-3]  NIST Chemistry WebBook for detail
Original Measurements:
   Hutchinson, C.A.; Lyon, A.M., Columbia University Report A-745, July 1, 1943.

 Variables:
   Temperature = 298 K

 Experimental Data:   (Notes on the Nomenclature)
  
t/°C102 * Mass Fraction w1 (compiler) 103 * Mole Fraction x1 (compiler)102 * w1/M1 [mol g**-1]
258.79 x 10-25.804.88 x 10-3
 Method/Apparatus/Procedure:
   A 1 to 15 volume ratio mixture of water and trichloromethane was introduced into an equilibration flask and then lowered into a water thermostat bath. The assembly was shaken mechanically for about 90 minutes at constant temperature. The amount of water in the organic  phase was determined by a modified Karl Fischer titration. The measurement was done in triplicate.The description was taken from a secondary source (ref. 1), because the original report is no longer available.

 Source and Purity of Materials:
   (1) Distilled.
   (2) Source not given. Purified and dried before use.

 Estimated Errors:
   Solubility: ± 0.1 x 10-4 avg. dev.
   Temperature: ± 0.05 K.
