Components of a non-idea) binary solution cannot be completely separated by fracti.o.nal distillation. Why?

The solution which boil at constant temperature like a pure liquid and possess same composition in liquid as well as vapour state are called azeotropes. The components of azetropes cannot be separated by fractional distillation. Only non-ideal solutions form azeotropes. Solutions with negative deviation form maximum boiling azeotrope and the solutions with positive deviation form minimum boiling azeotrope. The boiling point of an azeotrope is never equal to the boiling points of any of the components of the azeotrope. Answer the following question: The azeotropic solutions of two miscible liquids

  • Components, A and B, respectively of an ideal binary solution. If X_A represents the mole fraction of component A, the total pressure of the solution will be :

    A
    `p_A + x_A (p_B - p_A)`
    B
    `p_A + x_A (p_A - p_B)`
    C
    `p_B + x_A (p_B-p_A)`
    D
    `p_B + x_A (p_A-p_B)`

  • P_A and P_B are the vapour pressure of pure liquid components A and B respectively of an ideal binary solution. If x_A represents the mole fraction of component A ,the total pressure of the solution will be :
