Class 12 Chemistry Chapter 5 Surface Chemistry – Important Topics

Surface Chemistry is the study of the various phenomenon that takes place over chemical surfaces.

Adsorption: The process of attraction and aggregation of the molecules of a substance on the surface of a solid is known as adsorption.
Corrosion: The process through which the refined unstable metals convert themselves into more stable compounds is known as corrosion.
Crystallization: The type of technique that is used in order to purify the substances to separate solids from liquids is known as crystallization

Emulsions are colloidal solutions where both the dispersion medium and dispersed phase are in liquid state. They can be either oil in water or water in oil emulsions.

Surface chemistry finds its application in the process of Catalysis, Chromatography and Colloidal formations.
