Method/Apparatus/Procedure:
A colorimetric method was used. A 2.5 g trichloromethane sample was pipetted into a centrifuge tube containing 20 mL water. The tube was then vigorously shaken in a thermostat bath for two days. After shaking, the tube was centrifuged at high speed to give a clear upper water layer. From this layer the concentration of trichloromethane was determined by using a colorimetric method.
Source and Purity of Materials:
- Source and purity not given.
- Distilled (compiler).
Estimated Errors:
Ambient temperature: ±1 K (compiler).
Mass concentration (m/v) (1): ±1%.
Components:
- Trichloromethane, $\ce{ CHCl3 }$; [67-66-3] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
