प्रश्न
What type of azeotrope is formed by positive deviation from Raoult's law ? Give an example.
उत्तर
A minimum-boiling azeotrope is formed by solutions showing a large positive deviation from Raoult’s law at a specific composition.
Example: An ethanol–water mixture containing approximately 95% ethanol by volume.
