Method/Apparatus/Procedure:
A mixture of 10 to 20 mL 1,1-dichloroethane in 500 mL of an aqueous $\ce{MgSO4}$ solution in a bottle was placed in a water thermostat bath. The sample container was placed on a shaker and agitated until no more liquid droplets remained undissolved. One or more samples were syphoned out and the concen-tration of the 1,1-dichloroethane was determined using a Zeiss water interferometer.
Source and Purity of Materials:
- Commercial reagent, fractionally distilled before use.
- Kahlbaun chemical, certified grade.
- Distilled.
Estimated Errors:
Ambient temperature: ±0.01 K.
Mass concentration (m/v) (1): ±2%.
Components:
- 1,1-Dichloroethane, $\ce{ C2H4C12 }$; [75-34-3] NIST WebBook
- Magnesium sulfate, $\ce{ MgSO4 }$; [7487-88-9] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
