A method of separation of components from its solution using Distribution law is ___________________?
Correct answer: C. Solvent extraction
- A. Sublimation
- B. Crystallisation
- C. Solvent extraction
- D. Distillation
Explanation
Distribution law describes how a solute distributes itself between two immiscible solvents, and this principle is used in solvent extraction. The solute is transferred preferentially into the solvent in which it is more soluble. The likely mistake is choosing crystallisation, which separates a dissolved solid by differences in solubility with temperature rather than partitioning between solvents.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
