Method/Apparatus/Procedure:
A 20 cm
3
1,2-dibromoethane sample was mixed with 40 cm
3
aqueous electrolyte solution in a flask fitted with a thermostat jacket and a powerful stirrer. After a stirring time of 2-3 days, samples were taken from both phases for analysis. The bromine concentration was determined by adding HNO
3
to the solution and the free bromine was titrated with AgNO
3
solution. The water content of the organic rich phase was calculated by the method of Kariusu.
