Method/Apparatus/Procedure:
Samples were equilibrated for at least ten days in a water thermostat. Water analysis was done using an automatic Karl Fischer titration apparatus. The instrument accuracy was specified to be 1 %. All samples were handled with a hypodermic syringe which was weighted before and after each addition. The instrument was calibrated using a synthetic mixture of 1 % water in methanol.
Source and Purity of Materials:
(1) Distilled (compiler).
(2) Source and purity not given.
(3) Source not given, contained less than 0.1 dissolved material.
Estimated Errors:
Solubility: ± 1 %.
Temperature: ± 0.1 K.
