Conditions:
Room Temp: 283 - 353 $\pu{K}$
Compiler:
Methodology:
A mixture of pentachloroethane and water was preheated to the desired temperature before rapid mixing. The resulting mixture was thermostated and the equilibrium was maintained by vigorous stirring. The concentration of pentachloroethane in water determined by gas chromatography.
Sample Information:
- Solvay reagent, rectified before use, purity was 99.9% by GLC.
- Distilled.
Measurement Errors:
Ambient temperature: ±0.5 K.
Mass concentration (m/v) (1): Not specified.
System Components:
- Pentachloroethane, $\ce{ C2HCl5 }$; [76-01-7] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The temperature dependence of the solubility of pentachloroethane in water versus absolute temperature was expressed by the equation:
log10 (S/mol dm-3)=2070/(T/K)-16.412+0.0230 (T/K), where S=solubility, and T=absolute temperature.
The temperature interval covered by the above equation is from 283 to 353 K. For example, the calculated solubility derived from the above equation is 4.96×10-2 (100 w1) at 298.15 K (compiler).
