Which of the following is true when components forming an ideal solution are mixed?

For an ideal solution of two components A and B, which of the following is true?

formation of a solution form two components can be considered as (i) Pure solvent rarr separated solvent molecules, DeltaH_(1) (ii) Pure solute rarr separated solute molecules, DeltaH_(2) (iii) separated solvent and solute molecules rarr solution, DeltaH_(3) Solution so formed will be ideal if

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
