 Method/Apparatus/Procedure:
   The aqueous electrolyte solutions were saturated with tetrachloroethene in thermostated flasks fitted with stirrers and a mercury seal. Stirring was continued for several days until equilibrium was established. Samples were taken at specific  time intervals to check for equilibrium. The concentration of tetrachloroethene in the aqueous phase was measured by gas chromatography.

 Source and Purity of Materials:
   (1) Type "pure" (MRTU 6-00 No. 6590-70), redistilled and checked by GC before use.
   (2) Type "chemically pure".
   (3) Type "chemically pure".
   (4) Distilled.

 Estimated Errors:
   Solubility: See table above.
   Temperature: ± 0.2 K.
