Adsorption is a phenomenon in which a substance:a)Oxidises or reduces ...
Explanation:
Adsorption is a surface phenomenon in which a substance gets accumulated on the surface of another substance. The substance that gets adsorbed is called the adsorbate, and the surface on which it gets accumulated is called the adsorbent.
Types of Adsorption:
There are two types of adsorption, namely physisorption, and chemisorption.
Physisorption:
Physisorption is a type of adsorption in which the adsorbate is held onto the surface of the adsorbent by weak van der Waals forces. Physisorption is also known as physical adsorption.
Chemisorption:
Chemisorption is a type of adsorption in which the adsorbate is held onto the surface of the adsorbent by chemical bonds. Chemisorption is also known as chemical adsorption.
Examples of Adsorption:
Some examples of adsorption are as follows:
- Activated charcoal is used to adsorb impurities in the air and water.
- Silica gel is used to adsorb moisture from the air.
- Platinum is used as a catalyst in the chemisorption of hydrogen and oxygen during the Haber process.
Applications of Adsorption:
Some applications of adsorption are as follows:
- Adsorption is used in the purification of drinking water and wastewater treatment.
- Adsorption is used in the removal of impurities from gases and liquids.
- Adsorption is used in the separation of different components from a mixture.
Therefore, option C is the correct answer as adsorption is the phenomenon in which a substance accumulates on the surface of the other substance.
