Method/Apparatus/Procedure:
A bottle containing a mixture of 50 mL tetrachloromethane and 6 mL water was submerged into a water thermostat bath for two days. The concentration of water in the organic phase was determined by a conventional Karl Fischer deadstop backtitration. The determination was carried out in triplicate. A detailed description of the complete procedure is given in a Ph.D. thesis [1].
Source and Purity of Materials:
- Distilled and deionized.
- Fisher - C199, washed with $\ce{H2SO4}$ and $\ce{K2CO3}$ solutions and finally with water. Dried over silica gel and fractionally distilled. Purity was better than 99.8%.
Estimated Errors:
Ambient temperature: ±0.1 K.
Mass concentration (m/v) (1): ±0.2 c1 std. dev.
