FAQs on Balancing Redox Reactions using Oxidation Number Method Video Lecture - Chemistry for JEE Main & Advanced

1. How do you determine the oxidation number for each element in a redox reaction?

Ans. To determine the oxidation number for each element in a redox reaction, you need to follow the rules based on the periodic table. For example, the oxidation number of an element in its elemental form is 0, while in a monatomic ion, the oxidation number is equal to the charge of the ion. Additionally, the sum of oxidation numbers in a neutral compound is 0, and in a polyatomic ion, it is equal to the charge of the ion.

2. What is the oxidation number method used for balancing redox reactions?

Ans. The oxidation number method is used to balance redox reactions by assigning oxidation numbers to each element involved in the reaction. By tracking the changes in oxidation numbers of the elements, one can determine which elements are oxidized and reduced. The coefficients of the reactants and products are then adjusted to ensure that the total increase in oxidation numbers equals the total decrease.

3. Can the oxidation number method be used to balance redox reactions in acidic and basic solutions?

Ans. Yes, the oxidation number method can be used to balance redox reactions in both acidic and basic solutions. In acidic solutions, H+ ions and H2O molecules can be added to balance the hydrogen and oxygen atoms, while in basic solutions, OH- ions are added in addition to H2O molecules to balance the charges. The overall redox reaction remains the same, but the additional ions help balance the equation.

4. Why is it important to balance redox reactions using the oxidation number method?

Ans. Balancing redox reactions using the oxidation number method is important because it ensures that the law of conservation of mass and charge is obeyed. By balancing the reaction, one can accurately determine the stoichiometry of the reactants and products involved. Additionally, balanced redox reactions are essential in various chemical processes and industries.

5. What are some common mistakes to avoid when using the oxidation number method to balance redox reactions?

Ans. Some common mistakes to avoid when using the oxidation number method include incorrectly assigning oxidation numbers to elements, not accounting for changes in oxidation numbers during the reaction, and forgetting to balance the charges of the reactants and products. It is important to double-check the oxidation numbers and overall equation to ensure accuracy in balancing redox reactions.
