1. Introduction to oxidizing agents Submitted to: Miss Rukhsana Submitted by: Hassan khalid Roll no. 3216 (249148) Semester: 7 th morning

2. What is oxidation..? Oxidation is a loss of electrons gain of oxygen loss of hydrogen Oxidation

3. Oxidizing Agent What is oxidizing agent an oxidizing agent (oxidant, oxidizer), or  oxidising agent ( oxidiser ) is a substance that has the ability to oxidize other substances — in other words to accept their electrons.

4. Definition As an electron acceptor: Electron acceptors participate in electron-transfer reactions. T he oxidizing agent is called an electron acceptor. The reducing agent is called an electron donor.

5. Definition As an atom-transferring substance An oxidizing agent transfers oxygen atoms to a substrate. The oxidizing agent can be called an oxygenation reagent or oxygen-atom transfer (OAT) agent.

6. Common oxidizing agents Chromic acid, potasaium permanganate, Oxygen Hydrogen peroxide Potassium nitrate Sodium perborate Sodium bismuthate Ozone Hypochlorite Peroxydisulpuric acid Fluorine, chlorine Chromium trioxide Nitrous oxide Peroxydisulpuric acid

7. Factors Affecting the Oxidizing and Reducing Property: Ionisation potential. Electropositivity or electronegativity . Atomic size. Metallic and non-metallic character. Number  of  valence electrons.

8. Applications Bleaching of fabrics. Purification of water. Combustion of fuel involves the use of an oxidizing agent. Storage of energy in batteries. Vulcanization of rubber (increasing the strength and the elasticity of rubber).
