Method/Apparatus/Procedure:
An excess amount of tribromomethane with water was introduced into 30 ml centrifuge tubes that were closed with a screw cap. The tubes were rotated for 3 days inside a temperature controlled chamber at 10, 20, and 30
o
C, respectively. Samples were taken from the tubes and analyzed by gas chromatography after liquid-liquid extraction. The experiments were carried out in duplicates.
Source and Purity of Materials:
(1) Source and purity not given.
(2) Distilled and deionized.
Estimated Errors:
Solubility: ± 3.9 %.
Temperature: ± 0.5 K.
