FAQs on (L-1) Surface chemistry -- Basics of Absorption & Adsorption -- NEET JEE -- By Arvind Arora Video Lecture - Class 12

1. What is the difference between absorption and adsorption?

Ans. Absorption refers to the process where a substance is taken in or absorbed by another substance, such as a liquid being soaked up by a sponge. On the other hand, adsorption is the process where molecules of a substance adhere to the surface of another substance, forming a thin layer. The key difference between the two is that absorption involves the penetration of a substance into the interior of another substance, while adsorption involves the adherence of a substance onto the surface of another substance.

2. What are some examples of absorption in everyday life?

Ans. There are several examples of absorption in everyday life. Some common examples include: 1. Absorption of water by a sponge or paper towel. 2. Absorption of ink by a piece of paper. 3. Absorption of nutrients by the roots of plants. 4. Absorption of medicine by the human body. 5. Absorption of oil by a piece of bread.

3. What are some examples of adsorption in everyday life?

Ans. Adsorption is common in various aspects of everyday life. Here are a few examples: 1. Adsorption of gases by activated charcoal in air filters. 2. Adsorption of odors by baking soda in refrigerators. 3. Adsorption of color molecules by clothes during the washing process. 4. Adsorption of pollutants by activated carbon in water filters. 5. Adsorption of dyes by hair during hair coloring.

4. What is the significance of surface area in absorption and adsorption processes?

Ans. Surface area plays a crucial role in absorption and adsorption processes. A larger surface area provides more sites for molecules to interact with, leading to increased absorption or adsorption. For example, activated charcoal has a high surface area due to its porous structure, making it effective in adsorbing gases and impurities. Similarly, the small intestine in the human body has a large surface area with villi and microvilli, which enhances the absorption of nutrients.

5. How can absorption and adsorption be utilized in environmental remediation?

Ans. Absorption and adsorption are widely used in environmental remediation to remove pollutants from air, water, and soil. For instance: 1. Activated carbon can be used to adsorb volatile organic compounds (VOCs) from contaminated air or water. 2. Zeolites can absorb heavy metals from industrial wastewater. 3. Plants with high absorption capacities, such as sunflowers and water hyacinths, can be used to absorb heavy metals from contaminated soil or water. 4. Clay minerals can absorb and immobilize organic contaminants in soil. These techniques help in cleaning up polluted environments and improving overall environmental quality.
