Method/Apparatus/Procedure:
The solubility was determined in a 50 cm
3
flask containing a weighed quantity of water. Dichloromethane was added dropwise to the water until the first excess drop created turbidity. A slight turbidity immediately indicated the saturation point. .
Source and Purity of Materials:
(1) Laboratory sample dried with CaCl
2
and distilled. The middle fraction was used.
(2) Distilled.
Estimated Errors:
Solubility: ± 0.2 % by mass.
Temperature: ± 2.0 K.
