Room Temp: 273 - 348 $\pu{K}$

Methodology:
A 20 mL 1,2-dibromoethane sample was mixed with 40 mL water in a flask fitted with a thermostat jacket and a powerful stirrer. After the samples were stirred for 2-3 days, portions were taken from both phases for analysis. The bromine concentration was determined by adding $\ce{HNO3}$ to the solution and the free bromine was titrated with $\ce{AgNO3}$ solution. The water content of the organic-rich phase was calculated by the method of Kariusu [1].
Sample Information:
- Source and purity not given.
- Distilled.
Measurement Errors:
Ambient temperature: ±0.5 K (compiler).
Mass concentration (m/v) (1): Not specified.
System Components:
- 1,2-Dibromoethane, $\ce{ C2H4Br2 }$; [106-93-4] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
