The following Topics and Sub-Topics are covered in this chapter and are available on MSVgo:
Today, we are going to discuss in brief one of the most critical chapters of Chemistry – Redox Reactions. The term ‘reduction-oxidation’ is known as ‘redox’ in short. Redox is a kind of chemical reaction, where oxidation states of atoms are exchanged. If you break it down into two different actions – Oxidation and Reduction – you can analyze redox reactions. In redox reactions, we can see that the electrons are transferred between two reactants, loss of electron means ‘Oxidation’ and gain of electron means ‘Reduction’. Hence, a redox reaction is also known as Oxidation and Reduction reaction.
Let’s discuss below the individual definition of oxidation and reduction reaction with examples-
Now we will discuss the four types of redox reactions. The definitions with examples of these four types of redox reactions are stated below:-
Displacement reaction is divided into two types:-
The two examples of redox reactions are mentioned below:-
Balancing redox reactions means changing the oxidation number of the oxidizing agent and the reducing agent. In another sense it means to divide the redox reaction into two half equations – one is the reduction, and the other is oxidation.
Conclusion: ‘Redox reaction’ is an important chapter in Chemistry as for both the artificial and biological energy on this planet, redox reactions are the principal sources. Around 4-5 questions are asked in the examination from this section. In our daily life as well, we have experienced a redox reaction. To generate a DC when the battery is used, it uses a redox reaction to produce electrical energy.
1. What is a redox reaction? Explain with an example.
Redox reaction is the reaction that involves both reduction reactions and oxidation together. The composition of hydrogen fluoride is one of the examples of a redox reaction.
2. How do you identify redox reactions?
Redox reactions can be identified by observing the changes in the number of oxidations. We can split redox reaction into reductions half-reactions and oxidation.
3. How do you know if a reaction is a redox or Non-redox?
When the oxidation number changes in a reaction with an increase and decrease in number, the classification of that reaction is called redox, and when the oxidation does not change, this reaction is called non-redox.
4. What is the importance of redox reactions?
Redox reactions are important, as it is the principal source for both the artificial and the biological energy on this planet.
5. How is the energy released in redox reactions?
In redox reactions, when the potential energy of an electron is lost because of transfer, then energy is released.
