Question

any practical example of adsorption of gas on solid??

Answer 1

 

  Examples of Adsorption
Adsorption is the process whereby molecules of gases or liquids adhere chemically to the surface of a solid. It is frequently confused with absorption, whereby the particles of one substance become part of the matrix of a second substance. The solid to which the substance attaches is the adsorbent and the gas or liquid that becomes attached is the adsorbate. Adsorption is used in chromatography and to separate out unwanted substances in industrial and domestic applications.

Answer 2

Adsorption is defined as the deposition of molecular species onto the surface. The molecular species that gets adsorbed on the surface is known as adsorbate and the surface on which adsorption occurs is known as adsorbent. Common examples of adsorbents are clay, silica gel, colloids, metals etc.
