(i) Gas A is more soluble in water than ...

(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 ?

Text Solution

Verified by Experts

(i) `P_(A) = K_(H)X_(A)` [Henry's law]
As solubility decreases, K increases `[K_(H) = (P_(A))/(X_(A))]`
Hence, for Gas B at the same temperature, `K_(H)` value is higher.
(ii) Non-ideal solution having negative deviation shows the formation of maximum boiling. azeotrops.

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
