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:
   Nicloux, M.; Scotti-Foglieni, L., Ann. physiol. physicochim. biol. 1929, 5, 434-82.

Variables:
   Temperature = 286 K - 313 K

Method/Apparatus/Procedure:
   An all-glass apparatus which consisted of a liquid container with a mechanical stirrer and a gas storage tube was used for the measurements. Water was saturated with trichloromethane gas at a pressure of 750 mmHg. The absorbed gas volume was calculated from the  initial dry gas and final water vapor saturated gas volume. The amount of water was determined by measuring the mass of mercury displacement.

Source and Purity of Materials:
   (1) Laboratory reagent, Source and purity not given.
   (2) Distilled (compiler).

Estimated Errors:
   Solubility: Not specified.
   Temperature: ± 0.5 K (compiler).
