Question

Application of Nernst distribution law with reference to steam distillation

Answer 1

Explanation:

The distribution law states that a solute gets distributed between the two layers of immiscible solvents in such a way that the ratio of its concentration in each solvent becomes equal to the ratio of its solubility.

The formula for distribution law is as follows.

                    = Kd = Co/Cso

where,  

                    Co = molar concentration in organic layer

                    Cso = molar concentration in aqueous layer

                    Kd= distribution coefficient or constant

Applications of distribution law states are as follows.

Solubility of a solute can be measured.

One substance can be extracted from the solution containing various substances.

Used in high performance liquid chromatography.

Answer 2

Answer:

                    = Kd = Co/Cso

where,  

                    Co = molar concentration in organic layer

                    Cso = molar concentration in aqueous layer

                    Kd= distribution coefficient or constant
