Question

what is the differenc3 between absorb and adsorb.....with examples......dont copy from google​

Answer 1

Heya.....❤️❤️❤️

here is ur 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

Absorption is the process which takes place, when one substance enters the volume or bulk of another substance, while 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.

Here we noticed that there is the common term used in both the words is the ‘sorption‘, which describes the action performed by the absorption and adsorption. Though both are the vital process occurring in the day to day life, as well in chemical and biological labs.

Very slight though the significant difference between both the process will be considered in this content, along with a brief description.

BASIS FOR COMPARISON ABSORPTION ADSORPTION

Meaning The condition in which any substance (atoms, ions or molecules) is taken by or absorbed by another substance, especially in the solid or liquid material. In this condition the substances like gas, liquids or dissolved solids loosely adhere or stick to the surface of another substance which can be solid or liquid.

Kind of phenomenon Bulk phenomenon Surface phenomenon

Reaction Rate The reaction occurs at the uniform rate. The reaction rate increases slowly and attains equilibrium.

Heat exchange process Endothermic process. Exothermic process.

Concentration Does not change is constant throughout the medium. The concentration changes from bulk to the bottom of the absorbent.

Temperature No effect of temperature. Adsorption works at the lower temperature.

Application Cold storage, ice production, turbine inlet cooling, refrigerants. Air conditioning, water purification, synthetic resin, chillers
