Wehrmann, F.; Z. Elektrochem. 27, 379 (1921).
Conditions:
Room Temp: 263 - 303 $\pu{K}$
Compiler:
Methodology:
The titration method was used. Binary alcohol-water mixtures of known concentration and volume were put into Erlenmayer flasks, immersed in a constant temperature bath and then titrated with benzene until constant cloudiness was observed. Concentrations of alcohol-water mixtures were determined by density measurements. Results were reported in volume percentage.
Sample Information:
- Source not specified; chemically pure grade; used as received; $\rho^{15} = \pu{0.8835 g mL-1}$.
- Source not specified.
- Source not specified.
Measurement Errors:
Ambient temperature: Concentration ±0.3% relative error.
Mass concentration (m/v) (1): Not reported.
System Components:
- Ethanol, $\ce{ C2H6O }$; [64-17-5] NIST WebBook
- Benzene, $\ce{ C6H6 }$; [71-43-2] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
