NCERT Solutions for Class 11 Chemistry, Chapter 14 - Environmental Chemistry

In this chapter, you’ll study Environmental Chemistry. ‘Environmental Study’ is the study of biological, social, physical and chemical realms in our surroundings. ‘Environmental Chemistry’ is the study of the chemical processes that take place in water, air and soil environments. It deals with the origin, reactions, and effects of chemical elements in our environment. In this chapter, you’ll learn about environmental pollution, causes and effect of atmospheric, water and soil pollution. You’ll also learn what industrial waste is, how it is generated and used and finally some remedies to reduce environmental pollution. You’ll also be introduced to the concept of ‘Green Chemistry’ and its presence in our day to day lives.

Thus, an in-depth study of Class 11 Chemistry NCERT Solutions Chapter 14 will give you a good understanding of significant aspects of Environmental Chemistry.
