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:
   Sanemasa, I.; Arakawa, S.; Araki, M.; Deguchi, T., Bull. Chem. Soc. Jpn. 1984, 57, 1539-44.

 Variables:
   Temperature = 25 °C

 Prepared By:
   G.T. Hefter

 Experimental Remarks:
   The solubility of ethylbenzene in water at 25°C was reported to be 1.62 × 10–3 mol(1)/dm3 mol(1)/dm3 sln. Assuming a solution density of 1.00 kg/dm3 this corresponds to a solubility of 0.0172 g(1)/100 g sln, x1 = 2.92 × 10–5, calculated by the compiler.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   The apparatus used is described in detail in ref 1. The method involves the introduction of solute vapor (1) into liquid (2) by bubbling air through liquid (1) using a recirculating pump in a closed system. After solubility equilibrium was attained an aliquot of the saturated aqueous solution was withdrawn and analysed by solvent extraction - UV spectrophotometry.

 Source and Purity of Materials:
   (1) Analytical reagent grade source and purity not stated, used without further purification.
   (2) Deionized and redistilled; no further details given.

 Estimated Errors:

   Temperature: Not specified.
