Method/Apparatus/Procedure:
An excess of 1,1,2,2-tetrachloroethane was added to a stainless steel tube containing water and the tube was sealed. It was allowed to equilibrate during shaking for a week at 25 °C. After centrifugation, the sample was analyzed for radioactivity using a liquid scintillation counter. The solubility determination was repeated at least twice for each sample and the analysis was done in duplicate.
Source and Purity of Materials:
(1) New England Nuclear, used as received.
(2) Distilled.
Estimated Errors:
Solubility: ± 0.6 % std. dev.
Temperature: ± 0.3 K.
