Question

Adsorption is a surface phenomenon and absorption is a bulk phenomenon
if this is true enter $1$ if false enter $0$ .

Answer 1

Hint:Chalk dipped in ink is an example of adsorption and absorption simultaneously. The ink particles get absorbed in the chalk while the solution's water i.e, the water present in ink gets absorbed.

Complete step-by-step answer:The molecules undergoing absorption are taken up by the volume and in adsorption, the molecules are taken up by the surface.
Hence, adsorption is a surface phenomenon and absorption is a bulk phenomenon.
The correct option of this question is $1$ i.e, True.
If we have a vessel in which we have a solid bulky substance that is dissolved in a liquid which has solid particles dissolved in it, we know after some time these solid particles tend to accumulate on the surface of the bulky substance. Now, if we say this accumulation towards the bulky substance is because of the unbalanced or residual forces present on the solid body itself and this phenomenon is exactly what we term as adsorption. The only thing we make sure is that these particles do not penetrate the bulk itself.
The disappearance of one substance into another so that the absorbed losses its identifying characteristics while the absorbing substance retains most of its original physical aspects used in refining to selectively remove specific components from process streams.
Depending on the forces that are responsible for binding the molecules the adsorption is mainly divided into two types:

Physical adsorption	Chemisorption
It is temporary.	It is permanent.
It is not specific.	It is highly specific.
It is reversible.	It is non-reversible.

Note: Sorption is a process in which both adsorption (It is a process of accumulation of a substance at surface of the solid or liquid) and absorption (Accumulation of the substance within the bulk of a solid or liquid) takes place.
