   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.
