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

Which of the following animals is having longitudinal binary fission

Compreshension-II In non-ideal solutions, at one of the intermediate compostions, the total vapour pressure is highest and the boiling point is lowest. At this point, the composition of the liquid and vapour phase is same. So, if liquid mixture vapouriese at this point and vapours are condensed, teh condensate contains same compositon as present in original liquid mixture. it means at this point liquid behaves like a pure liquid and is called an Azeotropic mixture. Which of the following cannot form low boiling point azeotrope ?

Choose the correct answer :

represents the distillation of mixture of liquid A and liquid B which gives both of pure liquid A and B . Represents the azeotropic mixture of HNO_(3) and H_(2)O which distillation gives an azeotropic mixture and either of pure liquid. We cannot separate both the pure liquid, i.e., H_(2)O and HNO_(3) . At temperature T_(1) and composition Q , which of the following is true? a.Vapour phase is richer in B while liquid phase is richer in A . b.Distillation of composition Q gives only pure A . c.Distillation of composition Q gives only pure A and pure B . d.Distillation of composition Q gives higher percentage of B and A .

Compreshension-II In non-ideal solutions, at one of the intermediate compostions, the total vapour pressure is highest and the boiling point is lowest. At this point, the composition of the liquid and vapour phase is same. So, if liquid mixture vapouriese at this point and vapours are condensed, the condensate contains same compositon as present in original liquid mixture. it means at this point liquid behaves like a pure liquid and is called an Azeotropic mixture. A and B forms non-ideal solution showing positive deviation. Boiling point of pure A and B is 350 K and 380 K respectively. The solution will bpoil at (approximate)
