Glass Ball as Bullet Solubility System: Benzene with Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Benzene; C6H6; [71-43-2]  NIST Chemistry WebBook for detail
Original Measurements:
   Donahue, D.J.; Bartell, F.E., J. Phys. Chem. 1952, 56, 480-4.

 Variables:
   Temperature = One temperature: 25 °C

 Prepared By:
   A. Maczynski

 Experimental Remarks:
   The solubility of benezene in water at 25 °C was reported to be x1 = 4.2 x 10-4.

The corresponding mass percent calculated by compiler is 0.182 g(1)/100 g sln.

The solubility of water in benzene at 25 °C was reported to be x2 = 0.0031.

The corresponding mass percent calculated by compiler is 0.072 g(2)/100 g sln.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   Samples of (1) with (2) were placed in glass stoppered flasks and were shaken intermittently for at least three days in a water-bath held at 25 °C. The (1)-rich phases were analyzed for (2) content by the Karl-Fischer method and the (2)-rich phases were analyzed interferometrically.

 Source and Purity of Materials:
   (1) source not specified; best reagent grade; purified by fractional distillation and treatment with silica gel; purity not specified.
   (2) purified.

 Estimated Errors:

   Temperature: ± 0.1 K
