FAQs on Redox Reactions in One Shot (NCERT) Video Lecture - Chemistry Class 11 - NEET

1. What are redox reactions?
Ans. Redox reactions, also known as oxidation-reduction reactions, are chemical reactions in which there is a transfer of electrons between two species. One species loses electrons (oxidation) while another species gains electrons (reduction), resulting in a change in their oxidation states.
2. How can redox reactions be identified?
Ans. Redox reactions can be identified by the change in oxidation states of the elements involved. If an element's oxidation state increases, it undergoes oxidation, while if the oxidation state decreases, it undergoes reduction. The presence of a substance being oxidized and another being reduced indicates a redox reaction.
3. What is the importance of redox reactions in everyday life?
Ans. Redox reactions play a crucial role in various everyday life processes. For example, the process of respiration in living organisms involves redox reactions, where glucose is oxidized to produce energy. Rusting of iron, combustion of fuels, and photosynthesis are other examples of redox reactions that have significant implications in our daily lives.
4. What is the role of oxidation and reduction in redox reactions?
Ans. Oxidation and reduction are two integral parts of redox reactions. Oxidation involves the loss of electrons, increase in oxidation state, or gain of oxygen, while reduction involves the gain of electrons, decrease in oxidation state, or loss of oxygen. These processes occur simultaneously in a redox reaction, maintaining the overall charge balance.
5. How is the concept of redox reactions relevant in the field of medicine?
Ans. Redox reactions have significant relevance in medicine, particularly in understanding the functioning of antioxidants and free radicals. Antioxidants help prevent oxidative stress by undergoing redox reactions, donating electrons to neutralize free radicals. This understanding aids in the development of treatments for various diseases and conditions associated with oxidative stress, such as cancer, aging, and cardiovascular disorders.
