NCERT Grade 11 Chemistry Part 2 Chapter 8, Redox Reactions deals with the permutations and combinations between Reduction and Oxidation Reactions. A number of phenomena, both physical as well as biological, are concerned with redox reactions. These reactions find extensive use in pharmaceutical, biological, industrial, metallurgical and agricultural areas.
After studying this unit you will be able to identify redox reactions as a class of reactions in which oxidation and reduction reactions occur simultaneously; define the terms oxidation, reduction, oxidant (oxidising agent) and reductant (reducing agent); explain mechanism of redox reactions by electron transfer process; use the concept of oxidation number to identify oxidant and reductant in a reaction; classify redox reaction into combination (synthesis), decomposition, displacement and disproportionation reactions; suggest a comparative order among various reductants and oxidants; balance chemical equations using (i) oxidation number (ii) half reaction method; learn the concept of redox reactions in terms of electrode processes.
Through this chapter, students will learn the concepts of Classical Idea of Redox Reactions – Oxidation and Reduction Reactions, Redox Reactions in terms of Electron Transfer Reactions, Competitive Electron Transfer Reactions, Oxidation Number, Types of Redox Reactions, Balancing of Redox Reactions, Redox Reactions as the Basis for Titrations, Limitations of Concept of Oxidation Number, Redox Reactions and Electrode Processes. NCERT Grade 11 Chemistry Part 2 Chapter 8, Redox Reactions is a part of Unit 8. Unit 8, Unit 9, Unit 10 and Unit 11 hold a total weightage of 16 marks in the final examination.
