Non ideal solution

30 g of urea (M=60g mol^(-1) ) is dissolved in 846g of water. Calculate the vapour pressure of water for this solution if vapour pressure of pure water at 298 K is 23.8 mm Hg. (b) Write two differences between ideal solutions and non-ideal solutions,

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)

(i) Gas A is more soluble in water than Gas (B) at the same temperature. Which one of the two gases will have the higher value of K_(H) (Henry's constant) and why? (ii) In non-ideal solution, what type of deviation shows the formation of maximum boiling azeotropes ?

Assertion : Azeotropic mixtures are formed only by non - ideal solutions and they may have boiling points either greater than both the components or less than both the compontents. Reason : The composition of the vapour phase is same as that of the liquid phase of an azeotropic mixture.

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

When a solution of CHCl_(3) and acetone is formed, the solution is non-ideal with ………deviation from Raoult's law. The vapour pressure of such a solution will be ………….than the corresponding ideal solution.

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 Solutions which distill without any change in composition or temperature are called
