Glass Ball as Bullet Solubility System: Trichloromethane (chloroform) with Water

Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Trichloromethane (chloroform); CHCl3; [67-66-3]  NIST Chemistry WebBook for detail

Original Measurements:
   Masterton, W.L.; Gendrano, M.C., J. Phys. Chem. 1966, 70, 2895-8.

Variables:
   Temperature = 298 K

Prepared By:
   A. L. Horvath

Experimental Data:   (Notes on the Nomenclature)
  
t/°CConcentration c1 [mol m**-3]102 * Mass Fraction w1 (compiler) 103 * Mole Fraction x1 (compiler)
2573.88.98 x 10-25.92
Method/Apparatus/Procedure:
   Trichloromethane was equilibrated with water in an apparatus described elsewhere (ref. 1). The equilibration was allowed to take place for 2 days with the entire apparatus immersed in a water bath. The organic phase was analyzed for water by the Karl Fischer method  (dead-stop end point). The microburet used for the titration was read to ± 0.01 cm3. All titrations were carried out in an atmosphere of dry nitrogen.

Source and Purity of Materials:
   (1) Distilled.
   (2) Source not given. Reagent grade, washed with distilled water and the purity was checked with GC.

Estimated Errors:
   Solubility: ± 0.2 x 10-3 avg. dev.
   Temperature: ± 0.05 K.
