Method/Apparatus/Procedure:
The equilibrations were done over periods from 2 to 1seven days (average 7-10 days). Gravimetric analysis was the basis for the concentration determinations. The solute was placed in a spiral tube and weighed. Then, a known amount of water was passed through the tube and it was re-weighed. The weight loss and the mass of the water passed through the tube gave the solubility value directly.
Source and Purity of Materials:
- Synthesized from benzene and chlorine, recrystallized from abs. ethanol, MP = 53°C. The purity of the product was checked by elemental analysis.
- Source and purity not specified.
Estimated Errors:
Ambient temperature: ±0.5 K.
Mass concentration (m/v) (1): >10% (evaluated on the basis of deviations from the averages).
Components:
- 1,4-Dichlorobenzene, $\ce{ C6H4Cl2 }$; [106-46-7] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
