प्रश्न
Which of the following binary mixtures will have same composition in liquid and vapour phase?
(i) Benzene - Toluene
(ii) Water-Nitric acid
(iii) Water-Ethano
(iv) n-Hexane - n-Heptane
उत्तर
(ii) Water-Nitric acid
(iii) Water-Ethano
Explanation:
Non-ideal solution mixtures with same composition in liquid and vapour phase are azeotropes. Water-nitric acid has maximum boiling azeotrope and water-ethanol has a minimum boiling azeotrope.

Components of a binary mixture of two liquids A and B were being separated by distillation. After some time separation of components stopped and composition of vapour phase became same as that of liquid phase. Both the components started coming in the distillate. Explain why this happened.
The vapour pressures of two volatile liquids A and B at 25°C are 50 Torr and 100 Torr, respectively. If the liquid mixture contains 0.3 mole fraction of A, then the mole fraction of liquid B in the vapour phase is `x/17`. The value of x is ______.
