Method/Apparatus/Procedure:
The solubility was determined in a manometric apparatus consisting of a chamber and a transducer. The bottom plate of the chamber contained two wells; one was filled with mercury and the other was filled with introduced water and trichloromethane. The mixing and equilibrium between trichloromethane and water took place in the chamber under vigorous stirring. With the pressures before and after the equilibrium measured, the Ostwald coefficient was calculated from the chamber volume and the injected liquid volume.
