Which of the following binary mixtures will have same composition in liquid and vapour
phase?
A
Benzene-toluene
B
Water-nitric acid
C
Water-ethanol
D
-hexane - 
-heptane
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(b,c) Mixtures having same composition in liquid and vapour phase are known as azeotropes.
Azeotropes boils at same temperature. Here, water-nitric acid and water-ethanol mixtures are nonideal solution. Hence, water-nitric acid and water-ethanol are examples of azeotropes. While benzene-toluene and n-hexane- 
-heptane are examples of ideal solution.
