Glass Ball as Bullet Solubility System: Toluene with Water

Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Toluene; C7H8; [108-88-3]  NIST Chemistry WebBook for detail

Original Measurements:
   Johnson, J.R.; Christian, S.D., J. Chem. Soc. A. 1966, 77-8.

Variables:
   Temperature = One temperature: 25 °C

Prepared By:
   A. Maczynski and Z. Maczynska

Experimental Remarks:

   The solubility of water in toluene at 25 °C was reported tobe 0.0274 mol (2) dm-3 sln.
the corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.0572 g(2)/100 g sln and 2.92 x 10-3. The assumption that 1 dm3 sln = 862 g sln was used in the calculation.

Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   The apparatus described in ref 1 was used without modification. Samples were equilibrated in a constant-temperature water-bath maintained at 25 ± 0.1°C. Water solubilities were determined by using a Beckman Model KF-3 Aquameter.

Source and Purity of Materials:
   (1) source not specified; certified or reagent grade; distilled through a 30-plate Oldershaw column.
   (2) not specified.

Estimated Errors:
   Solubility: ± 0.0005 mol(2) dm-3 sln (type of error not specified)
   Temperature: ± 0.1 K
