of an aqueous KCl solution in a bottle was placed in a water thermostat bath. The sample container was placed on a shaker and agitated until no more liquid droplets remained undissolved. One or more samples were syphoned out and the concentration of the 1,1-dichloroethane was determined using a Zeiss water interferometer.
Source and Purity of Materials:
(1) Commercial reagent, fractionally distilled before use.
(2) Kahlbaum chemical, certified grade.
(3) Distilled.
Estimated Errors:
Solubility: ± 2 %.
Temperature: ± 0.01 K.
