 Variables:
   Temperature = 293 K

 Prepared By:
   W. E. Acree, Jr.

 Experimental Data:   (Notes on the Nomenclature)
  
t/°CConcentration c1 [mol dm**-3]
20.00.00034
 Method/Apparatus/Procedure:
   Constant temperature bath, centrifuge, thermometer, and a spectrofluorimeter. Excess solute and solvent were placed in glass vials, pre-equilibrated for several hours at 60-80 °C, and then equilibrated at 20 °C for several additional hours. After equilibration and  centrifugation, concentrations determined from the measured absorbance using the Beer-Lambert law.

 Source and Purity of Materials:
   (1) Purity not given, commercial sample of unspecified source, was used as received.
   (2) Purity not given, commercial sample of unspecified source, was used as received.

 Estimated Errors:
   Solubility: c1: Unknown.
   Temperature: T/K: ± 2.
