The correct Answer is:
To solve the assertion and reason question, we will analyze both the assertion (A) and the reason (R) step by step. ### Step 1: Understand the Assertion The assertion states that the heat of neutralization of HCl and NaOH is the same as that of H₂SO₄ with NaOH. **Explanation:** - Heat of neutralization refers to the heat change that occurs when an acid reacts with a base to form water and a salt. - For strong acids like HCl and H₂SO₄ reacting with a strong base like NaOH, the heat of neutralization is generally constant and approximately -57.1 kJ/mol for each mole of water formed. ### Step 2: Understand the Reason The reason states that HCl, H₂SO₄, and NaOH are all strong electrolytes. **Explanation:** - Strong electrolytes are substances that completely dissociate into ions in solution. - HCl and H₂SO₄ are strong acids, meaning they completely ionize in water, while NaOH is a strong base that also completely dissociates into Na⁺ and OH⁻ ions. ### Step 3: Analyze the Relationship Between Assertion and Reason Both the assertion and the reason are correct. The heat of neutralization for strong acids and strong bases is indeed similar because they dissociate completely in solution, leading to a consistent amount of heat released during the neutralization reaction. ### Conclusion - Both the assertion (A) and the reason (R) are correct, and the reason correctly explains the assertion. ### Final Answer The correct option is that both A and R are true, and R is the correct explanation of A. ---
