The correct Answer is:
To analyze the given assertion and reason, we can break down the problem into clear steps: ### Step 1: Understand the Assertion The assertion states that "Redox reactions are also called neutralization reactions." **Analysis**: - Redox reactions involve the transfer of electrons between species, where one species is oxidized (loses electrons) and another is reduced (gains electrons). - Neutralization reactions, on the other hand, typically refer to the reaction between an acid and a base to form water and a salt. While they can involve electron transfer, they are not classified as redox reactions in the general sense. **Conclusion**: The assertion is **incorrect**. ### Step 2: Understand the Reason The reason states that "The number of electrons gained or lost in the reaction are balanced." **Analysis**: - In redox reactions, it is indeed true that the number of electrons lost by the oxidized species must equal the number of electrons gained by the reduced species. This is a fundamental characteristic of redox reactions, ensuring that charge is conserved. **Conclusion**: The reason is **correct**. ### Step 3: Determine the Relationship Between Assertion and Reason Now, we need to evaluate the relationship between the assertion and the reason. - Since the assertion is incorrect and the reason is correct, we can conclude that the assertion does not support the reason. ### Final Conclusion - The assertion is false, and the reason is true. Therefore, the statement "Redox reactions are also called neutralization reactions" is incorrect, while the statement about the balance of electrons in redox reactions is true. ### Summary - Assertion: Incorrect - Reason: Correct

Balancing redox reaction by ion-electron method Chemical reactions which involve oxidation and reduction (redox reactions) can also be balanced by using the ion-electron method or half-equation method. This method of balancing redox reactions is based upon the principle that electrons lost during oxidation halfreaction of any redox reaction are equal to the electrons gained during reduction half-reaction. Balance the redox reaction ion-electron method: Zn + NO _(3) ^(-) to Zn ^(2+) + NH _(3) ^(+) (acidic medium)
