Components:

(1) Triiodomethane, CHI₃; [75-47-8] NIST WebBook
(2) Water, H₂O; [7732-18-5] NIST WebBook

Original Measurements

Dehn, W. M.; J. Am. Chem. Soc. 1917, 39, 1399-404.

Variables:

Ambient temperature: 293 - 298 K

Prepared by:

A.L. Horvath

Method/Apparatus/Procedure:

Excess triiodomethane in 5 cm³ water samples were enclosed in small vials which, when stoppered, were shaken until equilibria were established. The solutions were filtered into weighed crucibles and reweighed. After drying in vaccum desiccators, the crucibles were again weighed and the loss of water calculated. No great accuracy was claimed for the experiments.

Source and Purity of Materials:

1. From reliable firms; "not always pure."
2. Distilled (compiler).

Estimated Errors:

Ambient temperature: ±5 K.
Mass concentration (m/v) (1): Not specified.
