Variables:

Room Temp: 25.0 °C

Prepared by:

A.L. Horvath

Method/Apparatus/Procedure:

Equilibrium between the water and chlorobenzene was established by stirring the sample in a sealed flask [1] with a magnetic stirrer for 48 hours. The sample was filtered through a glass-wool plug and the chlorobenzene was extracted with 2,2,4-trimethylpentene. The optical density was determined spectrophotometrically [2]. Five parallel determinations were made. The reported work was based upon a Ph.D. dissertation [3].

Source and Purity of Materials:

1. Commercial reagent of analytical grade distilled through a column resulting in a more than 99% pure sample.
2. Distilled, deionized, and degassed.

Estimated Errors:

Ambient temperature: ±0.05 K.
Mass concentration (m/v) (1): ±1.7%.
