Surface Chemistry Class 12 Notes


Surface chemistry is a branch of chemistry in science that deals with phenomena occurring at surface or inter-surface of two-phases, i.e. at the boundary of the two surface or phases. These includes surfaces that can be solid-liquid, solid-gas, liquid-gas and solid-vacuum interfaces.

Important terms related with surface chemistry:

Adsorption- The phenomenon of attracting and retaining the molecule on the surface. The substance which is absorbed is called as ascorbate and the surface in which substance got absorbed is called as absorbent.

The reverse process for absorption is known as desorption which is done at high temperature and low pressure.
