An azeotropic solution of two liquids has a boiling point lower than either of them when it
A
Shows negative deviation from Raoult's law
B
Shows no deviation from Raoult's law
C
Shows positive deviation from Raoult's law
D
Is saturated
Answer
Shows positive deviation from Raoult's law
Explanation
Solution
Positive deviation from Raoult's law implies higher vapour pressure and thus lower boiling point.
