The correct Answer is:
To solve the question regarding the assertion and reason about the lead storage battery, we will analyze both statements step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "Lead storage battery does not require a salt bridge." - This is true because lead storage batteries, also known as lead-acid batteries, operate using a single electrolyte solution (sulfuric acid) and do not require a salt bridge to maintain electrical neutrality. 2. **Understanding the Reason**: - The reason provided is "The solid nature of each oxidizing agent and reducing agent prevents direct contact." - In lead storage batteries, the oxidizing agent (PbO2) and the reducing agent (Pb) are in solid form, which indeed prevents them from coming into direct contact with each other. This solid state allows the reactions to occur without the need for a salt bridge. 3. **Analyzing the Reactions**: - At the anode, lead (Pb) is oxidized to lead sulfate (PbSO4), and at the cathode, lead dioxide (PbO2) is reduced to lead sulfate (PbSO4). - The overall reaction involves the conversion of lead and lead dioxide into lead sulfate, which occurs in the presence of sulfuric acid. 4. **Conclusion**: - Since both the assertion and the reason are true and the reason accurately explains the assertion, we conclude that the assertion is correct and the reason is correct as well. - Therefore, both statements are true, and the reason supports the assertion. ### Final Answer: Both the assertion and reason are true, and the reason correctly explains the assertion. ---

In acid-base titration react rapidly to neutralise each other. Equivalence point is a point at which the acid and the base (or oxidising agent and reducing agent) have beem added in equivalent quantities. The end point in the point at which the titration stops. since the purpose of the indicator is to stop the titration close to the point at which the acid and base were added in equivalent quantities, it is important that the equivalent point and the end point be as close as must change colour at a pH close to that of a solution of the salt of the acid base. Singificantly, the pH changes most rapidly near the equivalent point. The exact shape of a titration curve depends on K_(a) and K_(b) of acid and base. The suitable indicator for the titration is
