what is meant by adsorption and what are they???
Answers
Answer:
Absorption is the process which means to absorb something for example water is absorbed by the soil.
Explanation:
absorption is a physical or chemical phenomenon or a process in which atoms, molecules or ions enter some bulk phase – liquid or solid material. ... The process of absorption means that a substance captures and transforms energy.
Answer:
Adsorption is a process which involves the accumulation of a substance in molecular species in higher concentration on the surface. If we look at Hydrogen, Nitrogen and Oxygen, these gases adsorb on activated charcoal. Meanwhile, we have to note that adsorption is different from absorption. The two processes involve totally different mechanisms.
For the adsorption process, two components are required,
Adsorbate: Substance which is deposited on the surface of another substance. For example, H2, N2 and O2 gases.
Adsorbent: Surface of a substance on which adsorbate adsorbs. For example, Charcoal, Silica gel, Alumina.
