Method/Apparatus/Procedure:
   The equilibration between 1,1,2,2-tetrabromoethane and water was established in a flask with a stirrer. The entire apparatus was immersed in a thermostat. After equilibrium was established, samples of the mixture were taken for an x-ray  spectroscopic determination of bromine and a gas chromatograph analysis using a flame ionization detector. The values presented are averages from duplicate experiments at each temperature. The determination was also reported in a Ph. D. thesis.1

Source and Purity of Materials:
   (1) Fisher's reagent grade, used as received; d4 = 2.9632 g/cm3 and nD = 1.6363 both at 20 °C.
   (2) Distilled.

Estimated Errors:
   Solubility: ± 1.0 %.
   Temperature: ± 0.2 K.
