FAQs on Oxidation & Reduction Video Lecture - Chemistry Class 11 - NEET

1. What is oxidation and reduction?
Ans. Oxidation is a chemical process in which a substance loses electrons, resulting in an increase in its oxidation state. Reduction, on the other hand, is a process in which a substance gains electrons, leading to a decrease in its oxidation state.
2. How are oxidation and reduction related?
Ans. Oxidation and reduction are two complementary chemical reactions that often occur simultaneously. In a redox reaction, one substance is oxidized while another is reduced. This means that the substance undergoing oxidation loses electrons, and the substance undergoing reduction gains those electrons.
3. Can you provide examples of oxidation and reduction reactions?
Ans. Sure! An example of an oxidation reaction is the combustion of a hydrocarbon fuel, such as the burning of methane (CH4) in the presence of oxygen (O2). Methane is oxidized to produce carbon dioxide (CO2) and water (H2O). An example of a reduction reaction is the reaction between sodium (Na) and chlorine (Cl2) to form sodium chloride (NaCl). In this reaction, sodium gains an electron from chlorine, which is reduced.
4. What is an oxidizing agent?
Ans. An oxidizing agent is a substance that causes oxidation by accepting electrons from another substance. It itself undergoes reduction during the process. Common oxidizing agents include oxygen (O2), hydrogen peroxide (H2O2), and chlorine (Cl2). These substances are often used in chemical reactions to facilitate the oxidation of other substances.
5. What is a reducing agent?
Ans. A reducing agent is a substance that causes reduction by donating electrons to another substance. It itself undergoes oxidation during the process. Examples of reducing agents include metals like zinc (Zn) and hydrogen gas (H2). These substances are commonly used in various chemical reactions to facilitate the reduction of other substances.
