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

Variables:
   Temperature = One temperature: 25 °C

Prepared By:
   G.T. Hefter

Experimental Remarks:

   The solubility of benzene in water at 25 °C was reported to be 2.07 x 10-2 mol (1)/dm 3 sln. Assuming a solution density of 1.00 kg/dm3 this corresponds to a solubility of 0.162 g(1)/100 g sln, x1 = 3.73 x 10-4, 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 After solubility equilibrium was attained an aliquot of the saturated aqueous solution was withdrawn and analyzed by solvent extraction - UV spectrophotometry.

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

Estimated Errors:

   Temperature: not specified.
