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:
   Gross, P.M.; Saylor, J.H., J. Am. Chem. Soc. 1931, 53, 1744-51.

 Variables:
   Temperature = One temperature: 30 °C

 Prepared By:
   A. Maczynski and Z. Maczynska

 Experimental Remarks:
   The solubility of toluene in water at 30 °C was reported to be 0.57 g(1)/kg (2) and 0.0062 mol (1)/kg (2).
The corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.057 g(1)/100 g solution and 1.12 x 10-4.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   Saturated solutions were prepared by shaking in a thermostat and were analyzed by means of an interferometer. The instrument used was a combination liquid and gas interferometer made by Zeiss.

 Source and Purity of Materials:
   (1) Baker's CP analyzed grade; distilled; b.p. 110.74 ± 0.02°C
   (2) distilled.

 Estimated Errors:
   Solubility: 2.0% (from values of duplicate determinations)
