Original Measurements

Hutchinson, C. A.; Lyon, A. M.; Columbia University Report A-745, July 1, 1943.

Variables:

Room Temp: 25 °C

Prepared by:

A.L. Horvath

Method/Apparatus/Procedure:

A mixture of 1 to 15 volume ratio of solute to solvent was placed in an equilibration flask and then lowered into a thermostat water bath. The assembly was shaken mechanically for about 90 min. at constant temperature. The amount of water in the organic phase was determined by a modified Karl Fisher titration. The determination was done in triplicate. The description of the procedure was taken from a secondary source [1]. The original report is no longer available.

Source and Purity of Materials:

1. Distilled.
2. Source is not known, purified and dried before use.

Estimated Errors:

Ambient temperature: ±0.05 K.
Mass concentration (m/v) (1): ±1%.
