FAQs on N-factor calculation - Redox reaction Video Lecture - Physical Chemistry
| 1. What is the definition of N-factor in a redox reaction? |  |
Ans. In a redox reaction, the N-factor represents the number of moles of electrons transferred by one mole of a substance during the reaction.
| 2. How is the N-factor calculated for an element or compound? | |
Ans. The N-factor can be calculated by considering the change in oxidation number of the element or compound in the reaction. The change in oxidation number corresponds to the number of electrons gained or lost.
| 3. Can the N-factor be fractional? | |
Ans. No, the N-factor cannot be fractional as it represents the whole number of electrons transferred. However, it can be zero if there is no change in the oxidation number of the element or compound.
| 4. Why is N-factor important in redox reactions? | |
Ans. The N-factor is important in redox reactions as it helps determine the stoichiometry of the reaction. It is used to balance the equation by ensuring the conservation of mass and charge.
| 5. How does N-factor relate to the concept of equivalent mass? | |
Ans. The N-factor is directly related to the concept of equivalent mass. The equivalent mass of a substance is equal to its molar mass divided by its N-factor. It represents the mass of a substance that can react with or replace one mole of hydrogen or oxygen atoms in a redox reaction.
