Method/Apparatus/Procedure:
A known volume of water was mixed with trichloromethane in an Erlenmeyer flask. The flask was immersed in a water bath and magnetically stirred. Samples were removed for analysis at regular intervals. All samples were analyzed using a gas-liquid chromatograph equipped with an electron capture detector. The solubility given is the average of five consecutive samples with less than 5 % variation.
Source and Purity of Materials:
- Source not given. Analytical standard grade, greater than 95% purity.
- Distilled and run through a resin column before use.
Estimated Errors:
Ambient temperature: ±0.5 K.
Mass concentration (m/v) (1): 5% variation of 5 samples.
Components:
- Trichloromethane, $\ce{ CHCl3 }$; [67-66-3] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
