Chapter Summary

--- PAGE 1 --- UNIT 7 REDOX REACTIONS Where there is oxidation, there is always reduction – Chemistry is essentially a study of redox systems. Objectives 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. Chemistry deals with varieties of matter and …
