Method/Apparatus/Procedure:
The equilibrium between water and trichloromethane was reached after the samples were left at least 40 hours in an equilibration vessel. The Karl Fischer titration method was used for the water analysis once equilibrium had been established. At least two samples were studied.
Source and Purity of Materials:
(1) Distilled.
(2) Source not given. Purity is > 99.9 %.
Estimated Errors:
Solubility: Not specified.
Temperature: ± 0.3 K.
