Solutions
For example, ethanol-water mixture (obtained by fermentation of sugars)
on fractional distillation gives a solution containing approximately 95%
by volume of ethanol Once this composition, known as azeotrope
composition, has been achieved, the liquid and vapour have the same
composition, and no further separation occurs The solutions that show large negative deviation from Raoult’s law
form maximum boiling azeotrope at a specific composition Nitric acid
and water is an example of this class of azeotrope
