Method/Apparatus/Procedure:
A 50 g trichloromethane sample was shaken with pure water in a 100 cm
3
Erlenmeyer flask. When equilibrium had been attained and the two phases separated, the organic phase was analyzed for water using the Karl-Fischer titration method. Five determinations were performed.
