Method/Apparatus/Procedure:
The determination of the solubility of water in tetrachloromethane was based on the infrared spectroscopic method. A UR-20 spectrophotometer was used with 2-cm cuvettes and the windows made of $\ce{KBr}$. The spectra were recorded at $\pu{3600 - 810 cm-1}$, and the absorbance at $\pu{3,702 cm-1}$ was found by the baseline method. Standard mixtures of tetrachloromethane and water were used for the calibration graphs. The results obtained were compared with measurements made by the methods of cloud point [1] and Karl Fischer titration.
Source and Purity of Materials:
- Distilled.
- "KhCh" brand, treated with $\ce{Na2CO3}$, dried with $\ce{CaCl2}$ and $\ce{P2O5}$ and distilled before use.
Estimated Errors:
Ambient temperature: ±0.5 K.
Mass concentration (m/v) (1): Not specified.
