Definition of Partially Miscible Liquids:
- Two liquids that dissolve into each other in limited amounts, forming two separate layers beyond a certain concentration.
Characteristics of Partially Miscible Liquid:
- Phase Separation: At certain concentrations and temperatures, these liquids separate into two distinct phases, each enriched in one of the components.
- Concentration Limits: The limits of miscibility are defined by the solubility curve, which depends on temperature and pressure.
- Examples: Water and phenol, water and nicotine, and diethyl ether and water.

Applications:
- Extraction Techniques: Used for selective solvent extraction in industries.
- Food and Beverage: Important for emulsion stability in products like salad dressings.
- Analytical Chemistry: Helps in compound separation based on solubility differences
