251.08 x 10-16.69 x 10-36.15
 Method/Apparatus/Procedure:
   An mixture of water and tetrachloroethene of about 1 to 5 volume ratio was placed in a sample vessel and rotated in a thermostat for 12 hours. After the equilibrium attained, samples were taken and filtered through cottonwool. The determination  of the water content was based upon the reaction with a-naphthoxydichlorophosphine. The evolved HCl gas was absorbed in water and titrated with NaOH solution.1 Two to three successive determinations were carried out with the samples.

 Source and Purity of Materials:
   (1) Distilled (compiler).
   (2) Commercial reagent, fractionated three times before use, b. p. = 124-125 &#deg;C.

 Estimated Errors:
   Solubility: ± 3.5 % mean dev.
   Temperature: ± 0.02 K.
