Separating Immiscible Liquids:
- Immiscible liquids in a mixture can separate into distinct layers.
- Heavier liquid settles at the bottom, while lighter liquid floats on top.
Difficult-to-Separate Mixtures:
Some mixtures, like turbid water, ink, and milk, contain tiny and light solid particles that remain evenly distributed and are hard to separate.
Chromatography:
- Chromatography is used to separate substances in a solution, especially when multiple substances are dissolved in small proportions.
- It is used in pharmaceutical science and scientific laboratories.
