Study Notes
Adsorption Process
- Adsorption is the process that involves the accumulation of a substance in molecular species in higher concentration on the surface.
Origin of the Term 'Adsorption'
- The term 'Adsorption' was first originated by physicist Wilhelm von Ostwald in 1881.
Difference between Absorption and Adsorption
- The main difference between absorption and adsorption is that absorption is a process where a substance is taken in by the entire volume of a material, whereas adsorption is a process where a substance accumulates on the surface of a material.
Particles Involved in Adsorption
- Typically, atoms, molecules, or ions are involved in adsorption.
Adsorption of Gases
- Hydrogen, nitrogen, and oxygen gases adsorb on activated charcoal.
Description of Adsorption Process
- Adsorption is often described as a surface phenomenon.
Substances Involved in Adsorption
- Typically, gases, liquids, or dissolved substances are involved in adsorption.
