Class 12 Chemistry Surface Chemistry. Adsorption and Absorption. Adsorption and Absorption. The dirt staying on the surface of the skin as a layer is termed as adsorbtion. Now consider applying soap solution to the shirt containing dirt. The soap solution is absorbed by the fabric and does not stay on the fabric as a layer The term adsorption was first coined in 1881 by a German physicist named Heinrich Kayser. Adsorption is often described as a surface phenomenon where particles are attached to the top layer of material. It normally involves the molecules, atoms or even ions of a gas, liquid or a solid in a dissolved state that is attached to the surface www.ncerthelp.com (Visit for all ncert solutions in text and videos, CBSE syllabus, note and many more) Adsorption Isostere These are the plot of temperature versus pressure for a given amount of adsorption Applications of Adsorption 1. For production of high vacuum. 2. Gas masks containing activated charcoal is used for breathing in coalmines
The adsorbent may be a solid or a liquid and the adsorbate may be a gas or a solute in some solution. Examples of Adsorption. 1) Adsorption of a gas by charcoal: Finely divided activated charcoal has a tendency to adsorb a number of gases like ammonia, sulphur dioxide, chlorine, oxygen, hydrogen, carbon monoxide, phosgene, etc. Charcoal acts as an adsorbent while gas molecules act as adsorbate Applications of Adsorption : → Some important applications of adsorption are as follow: In production of high vacuum : When activated charcoal is placed in a vessel then the remaining traces of air can be adsorbed by it. This results in creating very high vaccum. Chemistry Class 12 NCERT Solutions Chapter 6 General Principles and.
