FAQs on Oxidation and Reduction Video Lecture - General Awareness for SSC CGL

1. What is oxidation and reduction in the context of chemistry?
Ans. Oxidation is the loss of electrons by a molecule, atom, or ion, while reduction is the gain of electrons.
2. How are oxidation and reduction related to each other?
Ans. Oxidation and reduction are complementary processes that occur simultaneously in a chemical reaction. One species loses electrons (oxidation) while another gains those electrons (reduction).
3. What is the role of oxidation and reduction in redox reactions?
Ans. In redox reactions, oxidation and reduction occur simultaneously. Oxidation involves the loss of electrons, while reduction involves the gain of electrons. This transfer of electrons leads to changes in the oxidation states of the reactants.
4. How can oxidation and reduction be identified in a chemical reaction?
Ans. Oxidation can be identified by an increase in oxidation state, loss of hydrogen atoms, or gain of oxygen atoms. Reduction, on the other hand, is characterized by a decrease in oxidation state, gain of hydrogen atoms, or loss of oxygen atoms.
5. Can you provide an example of a redox reaction involving oxidation and reduction?
Ans. One example of a redox reaction is the reaction between iron and oxygen to form rust. In this reaction, iron undergoes oxidation (loss of electrons) to form iron oxide, while oxygen undergoes reduction (gain of electrons).
