Original Measurements
Mondain-Monval, P. I.; Quiquerez, J.; Bull. Soc. Chim. Fr. Mem. 7, 240 (1940).
Variables:
Room Temp: 298 $\pu{K}$
Prepared by:
Method/Apparatus/Procedure:
The analytical method was used. A sample of 100 mL of a ternary mixture, prepared by weight, was placed in a thermostat, agitated many times and then left for several hours to separate. The density and refractive index of each phase was measured. Inversion of density was observed.
Source and Purity of Materials:
- Source not specified; $d_{4}^{25}$ = 0.7853.
- Obtained in the laboratory; $d_{4}^{24}$ = 0.8622.
- Source not specified.
Estimated Errors:
Ambient temperature: Temp. ±0.02°C.
Mass concentration (m/v) (1): Not reported.
Components:
