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 often for a period of 6 to 8 hours. The solution was analyzed for water with the Beckman KF-3 Aquameter. The Karl Fisher 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 above.
Components:
- Tetrachloromethane, $\ce{ CCl4 }$; [56-23-5] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
