NCERT Solutions for Class 11 Chemistry, Chapter 8 - Redox Reactions

In this chapter, you’ll study about Redox Reactions. ‘Redox Reactions’ also known as oxidation-reduction reactions are chemical reactions that consist of the transfer of electrons between two species, wherein one species is reduced and the other one is oxidized. Oxidation is the decrease of electrons and reduction is the gain of electrons. A common example of a redox reaction is redox reaction of glucose in our body, rusting of iron, burning of fuel, operation of batteries in our electronic items, and so on. In this chapter you’ll learn different types of redox reactions, identifying redox reactions, balancing such reactions, drawbacks of oxidation number, redox reactions with respect to electrode processes and more.

Redox reactions have a lot of applications in the field of biology, agriculture, pharmaceutics and metallurgy.  Thus, an in-depth study of Class 11 Chemistry NCERT Solutions Chapter 8 will give you a good understanding of redox reactions.
