UNIT-6 TITRIMETRIC ANALYSIS ( redox REACTIONS)THE oxidation and reduction reactions in aqueous solutions involve thetransfer of electrons from one species to another. In the oxidation of asubstance electron(s) is (are) transfered from the species and in reduction,electron(s) is (are) gained by the species. Oxidation and reduction reactions occursimultaneously. A reaction, which involves simultaneous oxidation andreduction, is called a redox reaction. The titrations involving redox reaction arecalled redox titrations. You know that in acid-base titrations, indicators whichare sensitive to pH change are employed to note the end point.
The titrations involving redox reaction are called r edox titrations. Y ou know that in acid-base titrations, indicators which are sensitive to pH change are employed to note the end point. Similarly, in redox titrations there is a change in oxidation potential of the system. The indicators used in redox reactions are sensitive to change in ...
