Partition Law
Easychemistry
Nernst distribution law applies best to solute distributing between:
Select the correct option:
Solution
Incorrect! Answer:
Two immiscible solvents
- The Law: If a solute is added to a system of two immiscible (non-mixing) liquids, it distributes itself between the two layers in a constant ratio.
- Expression: Kd=C2C1 (at constant temperature), where C is the concentration in each layer.
- Application: This is the fundamental principle behind solvent extraction (e.g., extracting an organic compound from water into ether using a separating funnel).
- Limitations: It works strictly only if the solute remains in the same molecular state (no dissociation or association) in both phases.
