Method/Apparatus/Procedure:

An excess of 1,3-dichlorobenzene was added to water in a stainless steel centrifuge tube which was then sealed. The equilibrium was established by allowing the sample to stand, with intermittent shaking, for a week at constant temperature. The mixture was then centrifuged and aliquots of the solution were removed either by a pipet or syringe for analysis. Liquid scintillation counting with ¹⁴C-labelled solute was employed in the solubility determinations. The entire procedure was carried out at least twice and each analysis was also conducted in duplicate.

Source and Purity of Materials:

1. New England Nuclear, used as received.
2. distilled.

Estimated Errors:

Ambient temperature: ±0.3 K.
Mass concentration (m/v) (1): ±1.1% S.D.
