Volume 60. Halogenated Methanes with Water, p None

Original Measurements

Bell, R. P.; J. Chem. Soc. 1932, 2905-11.

Variables:

Room Temp: 288 - 298 $\pu{K}$

Prepared by:

A.L. Horvath

Method/Apparatus/Procedure:

An about 1 to 5 ratio of water/tetrachloromethane mixture was rotated in a thermostat for 12 hours. After the equilibrium was attained, samples were taken and filtered through cottonwool. The determination of the water content was based upon the reaction witha-naphthoxydichlorophosphine. The evolved $\ce{HCl}$ was absorbed in water and titrated with $\ce{NaOH}$ solution [1]. Two to three successive determinations were carried out with the tetrachloromethane.

Source and Purity of Materials:

1. Distilled (compiler).
2. Merck reagent, analytical grade, redistilled before use.

Estimated Errors:

Ambient temperature: ±0.02 K.
Mass concentration (m/v) (1): ±4.4% mean.
