Topics covered in Redox Reactions for JEE Advanced Chemistry.
Topics in Redox Reactions
1
Basic Concepts of Oxidation and Reduction
- Oxidation is the process of loss of electrons, addition of oxygen, removal of hydrogen, or increase in oxidation state
- Reduction is the process of gain of electrons, removal of oxygen, addition of hydrogen, or decrease in oxidation state
- Oxidation and reduction always occur simultaneously in a chemical reaction
2
Rules for Assigning Oxidation States
- Oxidation state of free elements is zero (Na, O₂, P₄)
- Oxidation state of monoatomic ions equals their ionic charge
- Hydrogen is usually +1 (except in metal hydrides where it's -1)
3
Types of Redox Reactions
- Combination reactions: A + B → C (at least one reactant must be elemental)
- Decomposition reactions: C → A + B (at least one product must be elemental)
- Displacement reactions: More reactive element displaces less reactive one
4
Balancing Redox Equations
- Two main methods: Oxidation Number Method and Ion-Electron Method
- Ion-Electron method is preferred for ionic reactions in solution
- Oxidation Number method is simpler for molecular equations
