Which of the following binary mixture will have same composition in liquid and vapour phase?

A

Benzene-toluene

B

Water-nitric acid

C

Water-ethanol

D

n-hexane-n-heptane

Text Solution

Verified by Experts

The correct Answer is:
B, C
Mixture having same composition in liquid and vapour phase are known as azeotropes. Azeotropes boils at same temperature.
Here, water-nitric acid water-entanol mixtures are non-ideal solution. Hence, water-nitric acid and water-ethanol ae examples of azeotropes.
While benzene-toluene and n-hexane -n heptanc are examples of ideal solution
