 Method/Apparatus/Procedure:
   The Alexejew's synthetic method of solubility determination was used.1 A fixed weight of tetrachloroethene and water was sealed in a tube and subjected to gradually increasing temperature with constant agitation. The appearance  of an opalescence or clouding was an indication of saturation temperature. The temperature was then allowed to fall and an observation made, while the tube was constantly agitated, to establish the temperature of the first appearance of opalescence. The observation was repeated several times.

 Source and Purity of Materials:
   (1) Source not given, treated with Na2CO3 solution and further purified by distillation.
   (2) Distillation

 Estimated Errors:
   Solubility: Not specified.
   Temperature: ± 1 K (compiler).
