7. REDOX REACTIONS
Redox reactions are crucial in understanding various chemical processes where oxidation and reduction occur simultaneously. This chapter explores the classical concept of redox, the electron transfer theory, and the application of oxidation numbers. Additionally, different types of redox reactions, methods for balancing them, and their significance in real-world applications are discussed.

What we have learnt
- Redox reactions involve simultaneous oxidation and reduction processes.
- Oxidation number helps to specify the oxidation state of elements in compounds.
- Various methods exist to balance redox reactions, including the oxidation number method and half-reaction method.
Key Concepts
- -- Redox Reaction
- A chemical reaction that involves a transfer of electrons between two species, leading to oxidation of one and reduction of another.
- -- Oxidation Number
- A value assigned to an element in a compound that represents the number of electrons lost or gained during a reaction.
- -- Oxidizing Agent
- A substance that gains electrons in a redox reaction, thereby causing another substance to be oxidized.
- -- Reducing Agent
- A substance that loses electrons in a redox reaction, thus causing another substance to be reduced.
