   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.
