Glass Ball as Bullet Solubility System: Cyclohexane with Water
Components:
   (1) Cyclohexane; C6H12; [110-82-7]  NIST Chemistry WebBook for detail
   (2) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
Original Measurements:
   Schwarz, F.P., Anal. Chem. 1980, 52, 10-15.

 Variables:
   Temperature = One temperature: 23.5 °C

 Prepared By:
   M.C. Haulait-Pirson

 Experimental Remarks:
   The solubility of cyclohexane in water at 23.5 °C was reported to be 0.0052 +/- 0.0002 g(1)/100 g sln.
The corresponding mole fraction, x1 was calculated by the compiler to be 1.1 x 10-5.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   An elusion chromatography method was used where (1) was the staionary phase and (2) the mobile phase. A transparent column was packed with an inert support (chromosorb P) coated with a known amount of the liquid solute (1). This solute column was connected to a water resevoir (connected to a compressed gas regulator). Water was forced through the column by the pressure of the compressed gas (ca. 14 kPa). As the total volume of water flowing through the column increased, a solute depleted zone, different in color from the stationary phase, developed and increased in length. The solubility is calculated from the amount of solute removed from the column, i.e. length of the solute depleted zone, and the volume of the water passed through the column. Many details about preparation of the solute about preparation of the solute column and calculation are given in the paper.

 Source and Purity of Materials:
   (1) 99.9% purity used without further purification.
   (2) distilled.

 Estimated Errors:
   Solubility: 4% (average std. dev.)
   Temperature: ± 1.5°C
