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

Variables:

Room Temp: 25.0 °C

Prepared by:

G. Jancso

Method/Apparatus/Procedure:

Between 25 and 100 mL of chlorobenzene and 1 to 2 mL $\ce{D2O}$ were introduced into a flask and shaken for about 90 min. The water bath temperature was maintained within ±0.05 °C. Then, a sample was taken and the dissolved $\ce{D2O}$ content was determined by a modified Karl Fischer titration as described in [1]. The original report was unavailable, but the method and the results have been described in sufficient detail in [1]. The solubility of $\ce{H2O}$ in chlorobenzene was also determined and found to be 0.00250 ± 0.00003 mol $\ce{H2O}$/ 100 g solution from three separate experiments.

Source and Purity of Materials:

1. Chlorobenzene was carefully purified and dried before use. Source and method not given.
2. Source not specified.

Estimated Errors:

Ambient temperature: ±0.5 K.
Mass concentration (m/v) (1): av. dev. ±1 × 10-5 mol D₂O/ 100 g solution
