Method/Apparatus/Procedure:
Samples of known composition (by volume) were prepared in glass tubes (diameter-15mm, length-200 mm) and sealed. These were placed in a thermostat and turbidity was observed after some (not reported) time. Eight series of measurements were made. The volume of alcohol was 2.00, 5.00, or 10.00 cm
3
. The volume of second component was constant in the series, while the volume of the third component differed 0.05-0.02 cm
3
from point to point. The results were reported in the paper as the volumes of each component added into the tube.
Source and Purity of Materials:
(1) Source not specified, 95% commercial reagent; purified with KMnO
4
, refulxed 1 day with CaO, distilled; purity 99.53% d(25°C)=0.7865.
(2) Merck, pure crystallized; distillation over Na.
(3) Doubly distilled.
Estimated Errors:
