Method/Apparatus/Procedure:
A 1 to 15 volume ratio mixture of water and tetrachloromethane was introduced into an equilibration flask and then lowered into a waterbath thermostat. 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 determination was done in triplicate. This description of procedure was taken from a secondary source [1]. The original university report is no longer available.
Source and Purity of Materials:
- Distilled.
- Source is not known. Purified and dried before use.
Estimated Errors:
Ambient temperature: ±0.05 K.
Mass concentration (m/v) (1): ±0.1 × 10-4 avg. dev.
