Glass Ball as Bullet Solubility System: Ethylbenzene with Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Ethylbenzene; C8H10; [100-41-4]  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 ethylbenzene in water at 25°C was reported to be 0.18 g(1) L–1 sln.

The corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.018 g(1)/100 g sln and 3.1 × 10–5. The assumption that 1.00 L-1 = 1.00 kg sln was used in the calculation.

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) L-1 sln (std. Dev. From 6 determinations).
