States of Matter - Result Question 51
####52. In a pair of immiscible liquids, a common solute dissolves in both and the equilibrium is reached. Then the concentration of the solute in upper layer is
[1994] (a) In fixed ratio with that in the lower layer
(b) Same as the lower layer
(c) Lower than the lower layer
(d) Higher than the lower layer.
Show Answer
Solution:
(a) By definition of Nernst distribution law.
When a solute is shaken with two immiscible
liquids, having solubility in both, the solute distributes itself between the two liquids in such a way that the ratio of its concentrations in two liquids is constant at a given temperature, provided the molecular state of the solute remains the same in both the liquids.
