FAQs on Index: Surface chemistry - Chemistry Class 12 - NEET

1. What is surface chemistry?
Ans. Surface chemistry is a branch of chemistry that deals with the study of chemical reactions occurring at the interface of two phases, typically between a solid and a liquid or gas. It involves the understanding of various phenomena such as adsorption, catalysis, and corrosion, which play a crucial role in industrial processes and natural systems.
2. What is adsorption?
Ans. Adsorption refers to the process where molecules or ions from a gas or liquid phase adhere to the surface of a solid substance. It occurs due to the attractive forces between the surface and the adsorbate molecules. Adsorption is commonly used in various applications such as wastewater treatment, purification processes, and gas separation.
3. What is catalysis in surface chemistry?
Ans. Catalysis in surface chemistry refers to the process where a substance, known as a catalyst, enhances the rate of a chemical reaction without being consumed in the reaction itself. In surface catalysis, the reactants are adsorbed onto the surface of the catalyst, leading to the formation of intermediate species that facilitate the reaction. This phenomenon is widely used in industries for the production of chemicals, fuels, and pharmaceuticals.
4. How does surface chemistry play a role in corrosion?
Ans. Surface chemistry plays a significant role in corrosion, which is the process of gradual deterioration of a material due to chemical reactions with its environment. The interaction between the corrosive agents and the surface of the material involves various surface chemical reactions, including adsorption, dissolution, and deposition of corrosion products. Understanding the surface chemistry of corrosion helps in developing effective corrosion prevention strategies and materials.
5. What are some practical applications of surface chemistry?
Ans. Surface chemistry has numerous practical applications. It is used in the manufacturing of catalysts for industrial processes, such as the production of ammonia or petroleum refining. Surface chemistry also finds applications in the development of advanced materials with specific surface properties, such as superhydrophobic coatings or self-cleaning surfaces. Additionally, it plays a crucial role in environmental science, including water and air pollution control, as well as in the field of biotechnology for drug delivery systems and biosensors.
