Question

$\huge\red{\mathscr Attention}$

Write difference between Adsorption and Absorption . ❤️​

Answer 1

Answer:

• Absorption v/s Adsorption
• ☺️Absorption is the process in which a fluid is dissolved by a liquid or a solid (absorbent).
• Absorption is the process which takes place, when one substance enters the volume or bulk of another substance.
• An example of absorption is soaking up spilled milk with a paper towel.
• ☺️Adsorption is the process in which atoms, ions or molecules from a substance (it could be gas, liquid or dissolved solid) adhere to a surface of the adsorbent.
• Adsorption is the condition which occurs on the surface of the substrate. In the case of adsorption, there are the intermolecular forces, which make the molecules to hold each other, but in absorption, there is soaking of the liquid or gas by the solid rather any forces applied on molecules.
• Examples of adsorbents are clay, silica gel, colloids, metals etc.

Answer 2

$\huge\underline\green{\sf Adsorption:-}$

• It involves high concentration of the gas or liquid at the surface of a substance.

• It is rapid in the beginning and slows down near the equilibrium.

• It is a surface phenomenon.

• It is a fast process.

$\huge\underline\green{\sf Absorption:-}$

• It involves uniform distribution of the Molecular species throughout the bulk

• It Occurs at a uniform rate.

• It Occurs throughout the body of the material .

• It is a slow process
