NEET Chemistry Surface Chemistry – Adsorption, Colloids & Catalysis

Surface Chemistry deals with the study of phenomena occurring at the surface or interface of substances. It plays an important role in industrial processes, catalysis, and the behavior of colloidal systems.

This chapter is an important and scoring topic in NEET Chemistry.

What is Surface Chemistry?

Surface chemistry focuses on reactions and interactions that occur at the surface of solids and liquids rather than in the bulk of the material.

Important Concepts

Adsorption

Adsorption is the accumulation of molecules on the surface of a substance. It is widely used in purification, catalysis, and industrial processes.

Catalysis

Catalysts increase the rate of chemical reactions without being consumed during the process. Many industrial reactions depend on catalytic activity.

Colloids

Colloids are heterogeneous systems in which very small particles are dispersed throughout another medium.

Emulsions

Emulsions are special types of colloidal systems where one liquid is dispersed in another liquid.
