JEE Main 2023 Redox Reactions and Electrochemistry Revision Notes

Let us look at each topic separately in detail, including their important sub-topics too.

JEE Main Revision Notes - Redox Reactions

This chapter explains the redox reaction. Besides, this oxidation and reduction reaction occurs at the same time. Also, three-tier conceptualization in texts, which are classical, oxidation number, and electronics, are presented. In addition, as per each conceptualization, we can see an oxidation, reduction, oxidising agent (oxidant), and a reducing agent (reductant) redox.

On the other hand, a consistent set of rules was handed over according to the reaction's rules. Also, both the oxidation numbers and ion-electrons are beneficial in writing the equations for the redox numbers.

Most notably, we can divide the oxidation reaction into four categories. These categories can be given as combination, decomposition, displacement, and disproportionation reactions. Besides, this concept also introduces the electrode and redox couple processes. Furthermore, the redox reactions find wide applications in the study of electrode and cell processes. Moreover, this chapter explains various rules of redox reactions. It also speaks about how to balance a redox reaction and what role the titration plays in the redox reaction, and in this chapter, it is represented in the form of a numerical problem.

In conclusion, this chapter comprises of various topics, such as oxidation number and its electronic representation, electrode processes and their balancing techniques, redox reactions and their rules, applications of redox reactions in cells, solubility issues of acid-base chemistry in aqueous solution, and finally the impact of titration on redox reactions.

JEE Main Revision Notes - Electrochemistry

This complete article deals with the electrochemistry revision notes. Electrochemistry focuses on the production of electricity from energy. Moreover, the release of this energy occurs during spontaneous chemical reactions. The chapter is specifically of paramount importance for both the practical and theoretical considerations as well. Most notably, the production of a huge count of metals and chemicals occurs by electrochemical methods. The conversion of chemical energy into electrical energy happens because of the batteries and fuel cells.

This chapter focuses on electrochemical reactions, electrode potentials, and calculations. Also, it mainly refers to anodic and cathodic processes involved in the oxidation-reduction reaction regarding transporting electrons. Besides that, metals usually act as an electrode in the galvanic cell. Furthermore, it calculates directly to determine the standard electrode potential and its unit; the voltage at 25 degrees Celsius is used for this calculation. It can be calculated by dividing the electromotive force (i.e., E°cell value-E°standard value). The electromotive force value is the total amount of potential required in a cell for a reaction to occur.

The difference between E°cell and E°standard can be a useful parameter called Gibbs free energy change or Gibbs free energy of a reaction. In addition, the importance of standard electrode potential lies in calculating the solubility products of various compounds from their standard electrode potentials. Moreover, this chapter presents the calculation of standard electrode potential in detail with numerical problems for students to understand better.

Reactions which result from the electrochemical processes are energy efficient and less polluting. Consequently, the revision notes of electrochemistry help in new innovative technologies that are eco-friendly. Moreover, electrochemistry enables the transmission of sensory signals from the brain to the cells and vice-versa. Without a shred of doubt, electrochemistry is a vast and interdisciplinary topic having huge implications in chemistry.

Sub-Topics of Electrochemistry

Let us look at the sub-topics that fall under Electrochemistry:

• Batteries - A battery is a device that contains electromechanical cells and external connections.

• The Conductance of Electrolytic Solutions - This refers to the ability of an electrolytic solution to conduct electricity

• Corrosion - This is a process by which the conversion of refined metal to a stable form happens

• Electrochemical Cells - This is a device, which generates electrical energy from reactions and uses this energy as well to create chemical reactions

• Electrolytic Cells and Electrolysis - The electrolytic cell is a kind of electrochemical cell, and electrolysis can be explained as a technique to use the direct electric current

• Fuel Cells - These are the electrochemical cells, and they can convert chemical energy into electricity

• Galvanic Cells - These are also the electrochemical cells by which oxidation-reduction reactions produce the electric energy

• Nernst Equation - This equation relates the electrochemical reaction's reduction potential to the chemical species activities, temperature, and also the standard electrode potential

• Variation of Conductivity & Molar Conductivity with Concentration - Both conductivity and molar conductivity certainly change with the electrolyte's concentration.
