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