Method/Apparatus/Procedure:
The solute isopiestic method was used without modification. The apparatus employed consisted of a closed vessel divided into two compartments, one for water and the other for the organic solvent. Equilibrium was attained after a period of 6 to 8 hours. Samples of the solution were analyzed for water with the Beckman KH-3 Aquameter. The Karl Fischer reagent was standardized against crystalline sodium tartarate dihydrate.
Source and Purity of Materials:
- Distilled.
- Source not given, certified or reagent grade, distilled through a 30-plate Oldershaw column before use.
Estimated Errors:
Ambient temperature: ±0.1 K.
Mass concentration (m/v) (1): See table above.
Components:
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
- 1,1,2,2-Tetrachloroethane, $\ce{ C2H2C14 }$; [79-34-5] NIST WebBook
