Class 11 Chemistry Chapter 8 Redox Reactions – Important Topics

Redox reaction is the combination of oxidation-reduction reaction wherein the oxidation number of a participating chemical species changes.

Oxidation Reaction: Oxidation is defined as the loss of electrons or an increase in the oxidation state of an ion or atom.
Reduction Reaction: Reduction is defined as the gain of electrons or a decrease in the oxidation state of an ion or atom.

Combustion Reaction: 22C₈H₁₈+ 25O₂ → 16CO₂(g) + 18H₂O

Disproportionation Reaction: 3ClO^-(aq) → ClO^3-(aq) + 2Cl^-(aq)

Single replacement Reaction: Zn(s) + 2HCl(aq) → ZnCl₂(aq) + H₂(g)

Oxidizing agents: Oxidising agent (also known as an oxidizer or oxidant) is a chemical species that tends to oxidise other substances, causing them to lose electrons and raises their oxidation state. Examples of Oxidizing agents include Halogens, Oxygen, Hydrogen Peroxide.

Reducing agents: A Reducing agent is an element (or compound) which loses one or more electrons to an electron recipient group. In a redox chemical process, it oxidises itself. Common reducing agents include metals, hydracids, lithium, iodine, reducing sugars.
