Chemistry Revision Notes for Class 12 Chapter 5 Surface Chemistry

Here is a brief discussion on the chapter 5 Surface Chemistry. Adsorption is surface phenomena, and therefore the molecules, atoms or ions accumulate at the surface. During this exothermic process, a film is created. This film is called adsorbent. There are two types of adsorption:

  • Reversible adsorption
  • Irreversible adsorption

Learn more about how adsorption is different from absorption, and some related terminologies such as adsorbent, adsorbate, interface, etc. with BYJU’S. The content below is authentic and easy to access. Class 12 students should have strong basics, and so we decided to come up with a perfect revision material.
