Glass Ball as Bullet Solubility System: Toluene with Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Toluene; C7H8; [108-88-3]  NIST Chemistry WebBook for detail
Original Measurements:
   Korenman, I.M.; Aref'eva, R.P., Zh. Prikl. Khim. 1978, 51, 957-8.

 Variables:
   Temperature = 25 °C

 Prepared By:
   A. Maczynski and Z. Maczynska

 Experimental Remarks:
   The solubility of toluene in water at 25 °C was reported to be 0.65 g(1)dm-3 sln. The corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.065 g(1)/100 g sln and 1.27 x 10-4.
The compiler's calculations assume a solution density of 1.00 g/mL.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   About 200-500 mL(2) was placed in a ground-joint glass cylinder and 20-50 mg of an insoluble indicator (dithizon, phenolphthalein, etc.) was added, and (1) was microburetted until the indicator floated to form a colored thin layer on the cylinder wall above the liquid layer. Blanks were made to determine the excess of (1).

 Source and Purity of Materials:
   (1) not specified.
   (2) not specified.

 Estimated Errors:
   Solubility: ± 0.01 g(1) dm-3 sln (standard deviation from 6 determinations).
