Glass Ball as Bullet Solubility System: Benzene with Sodium Chloride and Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Benzene; C6H6; [71-43-2]  NIST Chemistry WebBook for detail
   (3) Sodium Chloride; NaCl; [7647-14-5]  NIST Chemistry WebBook for detail
Original Measurements:
   Mackay, D.; Shiu, W.Y., Can. J. Chem. Eng. 1975, 53, 239-42.

 Variables:
   Temperature = One temperature: 25 °C
   Concentration = Salinity: 0-200 g(2)/kg sln

 Prepared By:
   M. Kleinschmidt and W. Shiu

 Experimental Remarks:
   The solubility of benzene in solutions of sodium chloride is reported in terms of the Setschenow equation:
           log(SoS) = KsCs
   where,So is the solubility of benzene in water (mg/L)
      S is the solubility of benzene in solution (mg/L)
      Ks is the Setschenow constant (L/mol)
     Cs is the concentration of sodium chloride (L/mol)
evaluating the equation for S over the range of Cs 0-4 mol/L, Ks = 0.1836 +/- 0.0072 (standard error) with So = 1779.5 +/- 16.4.

The corresponding mass percent and mole fraction, x1, at salinity = 35 g(2)/kg sln calculated by the compilers are 0.1340 g(1)/100 g sln and 3.227 x 10-4 assuming a solution density of 1.025 kg/L.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   Solubility was determined by vapor phase extraction and gas chromatograph analysis. This method does not require the preparation of saturated solutions and thus avoids one of the major sources of error of other methods.

 Source and Purity of Materials:
   (1) research grade, 99.9+%, from Phillips Petroleum Co.
   (2) and (3) not specified.

 Estimated Errors:
   Solubility: 95% confidence limit is about 8%
   Temperature: ± 0.1 K
