FAQs on Video: Oxidation Reduction Reactions (Hindi) Video Lecture - Class 10

1. What are oxidation reduction reactions?

Ans. Oxidation reduction reactions, also known as redox reactions, are chemical reactions that involve the transfer of electrons between two species. In these reactions, one species loses electrons (oxidation) while the other species gains electrons (reduction). This transfer of electrons allows for the formation of new compounds.

2. How can oxidation be identified in a redox reaction?

Ans. Oxidation can be identified in a redox reaction by looking at the change in oxidation state of an element. If the oxidation state of an element increases, it means that the element has undergone oxidation. For example, if the oxidation state of an element changes from 0 to +2, it has been oxidized.

3. What are some examples of oxidation reduction reactions?

Ans. Some examples of oxidation reduction reactions include the rusting of iron, combustion reactions (such as burning of fuels), and the reaction between acids and metals. In the rusting of iron, the iron undergoes oxidation while oxygen gains electrons and undergoes reduction.

4. How does oxidation reduction reactions play a role in everyday life?

Ans. Oxidation reduction reactions play a significant role in everyday life. For example, the process of respiration in living organisms involves the oxidation of glucose to produce energy. Additionally, the batteries we use in various electronic devices rely on redox reactions to generate electricity.

5. How are oxidation reduction reactions balanced?

Ans. To balance oxidation reduction reactions, the number of electrons lost in the oxidation half-reaction must be equal to the number of electrons gained in the reduction half-reaction. This can be achieved by multiplying the half-reactions by appropriate coefficients so that the total number of electrons is balanced. The balanced equations show the stoichiometry of the reactants and products involved in the redox reaction.
