The chart shows the results, which are unfortunately irregular for some unex- plained reason, there being in the usual way a very slow adjustment to the equilibrium conditions, after which the gas diffuses at a fairly regular rate. The diffusion constants are (vessel B), Vq â or 10^*^^ = a reasonable ad\ance on the former rates. The three curves for KCl solu- tions show that not until after the lapse of two weeks do definite rates appear. These essentially final rates are the ones taken. In each case there seems to be an adjustment of the gas (Oo, Ng), which actually diffuses, to the solution. 46. The Same, Continued.âOn further dilution with about an equal volume of water the density of the solution was p= at 21°, corre- sponding to grams in 100 grams of solution, or grams in 100 grams of water. Thus the vapor pressure became 7r' = 7r(i â ). The progress of the diffusion is given in table 27 and fig. 25. The latter shows marked irregularity at the beginning (as usual), but the curve be- comes fairly smooth when daily observations are replaced by weekly obser- vations. Clearly, therefore, the daily churning up of the solution during observation, usually at a relatively high temperature, is unfavorable to a steady progress of results. The locus, however, is not quite straight, for reasons which can not be inferred, as temperature was fairly constant. T.\ 27.âAir into air through KCl solution ( grams in 100 grams water).
