Colloidal State

OBJECTIVES

1. To start with need for the Colloidal State chapter.
2. To define colloids and types of colloidal systems.
3. To elaborate the solids in liquids (sols) including two preparation methods (dispersion, and aggregation).
4. To describe the purification methods of sols such as dialysis, electro dialysis, and ultrafiltration.
5. To describe properties of sols such as colour, optical, kinetic, and electrical properties.
6. To state stability of sols, protective action, Hardy–Schulze law, and gold number.
7. To state and describe in detail about liquids in liquids (emulsions), their types, preparation, and emulsifier.
8. To define liquids in solids (gels), their classification, preparation, properties, and inhibition.
9. To end the chapter ...
