Method/Apparatus/Procedure:
An accurate amount of tetrachloromethane was transferred into an Erlenmeyer flask containing a weighed amount of aqueous solution. The flask was rotated in a thermostat bath until equilibrium was established. The optical densities of different concentration of tetrachloromethane in the aqueous solutions were measured using water as the reference liquid. Duplicate experiments were made and the results averaged. The absorption spectra of tetrachloromethane in aqueous potassium sulfate solutions were determined using a Hilger spectrophotometer.
Source and Purity of Materials:
- Peking Chemical Factory, further purified by washing with $\ce{H2SO4}$, $\ce{NaOH}$ and water; dried over $\ce{CaCl2}$ and fractionated.
- Peking Chemical Factory, recrystallized twice before use.
- Distilled.
Estimated Errors:
Ambient temperature: ±0.5 K (compiler).
Mass concentration (m/v) (1): Not specified.
