...Crompton, Proc., 1901, 17, 61; and Kleern.-ui, Phil. Mag., 1910, [vi], 20, 665), depends on the assumption that the composition of the vapour is the same as that of the liquid. We should expect, therefore, that Trouton's equation will only hold for mixtures when the difference...

...boiling point — and when it is this particular mixture that is introduced into the vacuous space, that the composition of the vapour is the same as that of the liquid. In all other cases the vapour is richer in the more volatile of the two components into which...

...however, not have the same significance as that of a binary system. For in the case of a binary system the composition of the vapour is the same as that of the liquid phasis; for a ternary system only y, and y, are equal, but .r, and .r, differ. In such a point...

...the quantities of the two liquids originally present. For a maximum or minimum of the vapour-tension, the composition of the vapour is the same as that of the liquid, as is proved by the following consideration. Were it otherwise, the composition of the liquid...

...water than they themselves possess, and that for mixtures containing less than 25 per cent, of water the composition of the vapour is the same as that of the liquid : hence 75 per cent, is the maximum content of formic acid either in the boiling-vessel or in...

...distillation is quite different for the following reasons : the maximum or minimum vapour pressure, the composition of the vapour is the same as that of the liquid. Hence, it distils unchanged at a constant temperature (provided that the external pressure...

...1023 mol1. • azeotrope azeotrope is a mixture of two liquids that boils at constant composition, ie the composition of the vapour is the same as that of the liquid. Azeotropes occur because of deviations in Raoult's law leading to a maximum or minimum in the...

In both cases it stops suddenly at the critical...ethyl alcohol and carbon disulphide, water and phenol ti water and aniline. These mixtures, however, require further investigation, so that we will not discuss...
