Original Measurements
Clifford, C. W.; Ind. Eng. Chem. 1921, 13, 631-32.
Variables:
Room Temp: 298 - 301 $\pu{K}$

Method/Apparatus/Procedure:
The calcium chloride method was used for the determination of water in trichloromethane. The water was measured as the moisture abstracted from the samples by air and absorbed in two calcium chloride tubes. The tubes were weighed before and after absorption. For further details, see the paper by Clifford [1].
Source and Purity of Materials:
- Distilled (compiler).
- U. S. P. grade, used after dehydration with $\ce{CaCl2}$.
Estimated Errors:
Ambient temperature: ±0.5 K (compiler).
Mass concentration (m/v) (1): About 1 mg.
