Answer:
a mixture of two liquids which has a constant boiling point and composition throughout distillation are called azeotropes.
A solution that shows greater positive deviation from Raoult's law forms a minimum boiling azeotrope at a specific composition. For example, an ethanol-water mixture (obtained by fermentation of sugars) on fractional distillation yields a solution containing approximately 95% by volume of ethanol.
