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:
   Roddy, J.W.; Coleman, C.F., Talanta 1968, 15, 1281-6.

 Variables:
   Temperature = One temperature: 25 °C

 Prepared By:
   A. Maczynski and Z. Maczynska

 Experimental Remarks:
   The solubility of water in benzene at 25 °C was reported to be x2 = 3.23 x 10-3 and 0.0363 mol (2) dm-3 sln.
The corresponding mass percent value calculated by the compilers is 0.0747 g(2)/100 g sln.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   A method for measuring the solubility of (2) in (1) was based on the use of tritium tracer to monitor the recovery of (2) in a conventional gravimetric method and to measure tritum distribution between the aqueous and the organic phases.

 Source and Purity of Materials:
   (1) source not specified; thiophene free regent; recrystallized three times.
   (2) HTO at 5 Ci/mL, New England Corp.; diluted to about 1 mCi/mL.

 Estimated Errors:
   Solubility: better than 1% (type of error not specified).
