Surface Chemistry The branch of chemistry which deals with the nature of surfaces and changes occurring on the surfaces is called surface chemistry. Adsorption Adsorption is a surface phenomenon. It arises because of the unbalanced forces on the..

SURFACE CHEMISTRY

"Concentration of a substance on the surface and in the bulk of another substance n is known as sorption. The surface for sorption means a layer of thickness of about 100 nm from the outer surface of the substance. Sorption includes two simultaneous processes viz. i. Adsorption and ii. Absorption Adsorption : A..

SURFACE CHEMISTRY

This unit deals with some important features of surface chemistry such as adsorption, catalysis, colloids, emulsions etc. The term surface or interface as interpreted in surface chemistry refers to a region where two phases meet. Most of the physical and chemical processes as we encounter in..

Surface Chemistry

The study of the boundary separating two bulk phases is called surface chemistry. This boundary is also known as boundary surface or interface. It is expressed either by a hyphen or a straight vertical line. viz. solid-liquid or solid/liquid indicates the interface between two phases solid and liquid. If the gases a..
