Question

Write the difference between absorption and adsorption.

Answer 1

Hint: We know that absorption and adsorption are a different phenomenon. In absorption, the atoms enter into the bulk phase of a liquid or solid whereas adsorption substances adhere to the surface of the molecule.

Complete step by step answer:
Let us discuss the major differences between absorption and adsorption.

Absorption	Adsorption
Absorption is the condition in which the atoms, ions, or molecules are absorbed by another substance particularly in the solid or liquid material	Adsorption is the condition in which gas, liquid or, dissolved solids loosely stick to the surface of another substance especially in solid or liquid.
It is a bulk phenomenon	It is a surface phenomenon
Absorption reaction occurs at a uniform reaction rate	In Adsorption reaction, the rate of the reaction slowly increases and finally attains equilibrium
Absorption is an endothermic process	Adsorption is an exothermic process
There is no change in concentration.	In the Adsorption reaction the Concentration at the bottom of the absorbent is different from the bulk
The temperature does not affect the absorption process.	Adsorption occurs at a lower temperature.
The Absorption process is applied on cold storage, ice production, and in turbine inlet cooling	The Adsorption process is used in air conditioning, water purification, and in the synthesis of resin.

Note:
We must know that the Absorption process occurs in all living and nonliving organisms to intake the nutrients and to balance internal stability according to the changing environment. Adsorption is used in separation techniques like ion-exchange chromatography to separate the molecules by selective transfer of the liquid phase to the surface of the solid.
