Conditions:
Room Temp: 293 $\pu{K}$
Compiler:
Methodology:
The titration method was used to determine the binodal curve. The refraction indexes of mixtures were measured to construct the calibration curve, which was then used to find the concentration of ethanol in both phases at equilibrium.
Sample Information:
- Source not specified, dehydrated; distilled; BP = 78.0°C, $n_{D}^{20}$ = 1.3596.
- Source not specified; doubly distilled; BP = 68.5°C, $n_{D}^{26}$ = 1.3751.
- Doubly distilled.
Measurement Errors:
Ambient temperature: Not reported.
Mass concentration (m/v) (1): Not reported.
System Components:
- Ethanol, $\ce{ C2H6O }$; [64-17-5] NIST WebBook
- Hexane, $\ce{ C6H14 }$; [110-54-3] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
