1.	What are the Types of azeotropes? Explain with example.
Answer» Types of azeotropes: Minimum boiling azeotrope The non- ideal solutions showing positive deviation form minimum boiling azeotrope at a specific composition. Example: 95% ethanol and 5% water (by volume) Ethanol = 351.3 K , Water = 373 K, Azeotrope = 351.1 K Maximum boiling azeotrope The non- ideal solutions showing negative deviation form maximum boiling azeotrope at a specific composition. Example : 68% Nitric acid and 32% water (by mass) Nitric acid = 359 k, water = 373 k, Azeotrope = 393.5 K

Answer»

Types of azeotropes:

Minimum boiling azeotrope

The non- ideal solutions showing positive deviation form minimum boiling azeotrope at a specific composition.

Example: 95% ethanol and 5% water (by volume)

Ethanol = 351.3 K , Water = 373 K, Azeotrope = 351.1 K

Maximum boiling azeotrope

The non- ideal solutions showing negative deviation form maximum boiling azeotrope at a specific composition.

Example : 68% Nitric acid and 32% water (by mass)

Nitric acid = 359 k, water = 373 k, Azeotrope = 393.5 K
