Question

what will be the partition Coefficient expression during the association and dissociation of a solute

Answer 1

According to Partition law: “When a solute is dissolved in two immiscible liquids, in which the solute is soluble, the solute distributes itself between the two liquids in a way that the ratio of its concentration in the two liquid phases is constant.  

This can be seen by the equation:

$K_{D}=\frac{C_{1}}{C_{2}}$

C₁ and C₂, are the concentration of solute in the two phases.

$K_{D}$, is the partition constant.

Partition Coefficient expression during the association and dissociation of a solute:

Partition Coefficient expression during the association:

$K_{D}=\frac{C_{1}}{n\times \sqrt{C_{2}}}$  

Partition Coefficient expression during the dissociation:

$K_{D}=\frac{C_{1}}{C_{2}\times (1-\alpha )}$ ,

$(\alpha )$ , is the degree of dissociation.
