The correct Answer is:
To determine the values of X and Y for the neutralization reactions of HCl and H2SO4 with NaOH, we need to consider the number of hydrogen ions (H⁺) released by each acid and the stoichiometry of the neutralization reactions. ### Step-by-Step Solution: 1. **Identify the Acids and Their Properties:** - **HCl (Hydrochloric Acid):** It is a strong acid that dissociates completely in solution to release 1 mole of H⁺ ions per mole of HCl. - **H2SO4 (Sulfuric Acid):** It is also a strong acid, but it is diprotic, meaning it can release 2 moles of H⁺ ions per mole of H2SO4. 2. **Neutralization Reaction of HCl:** - The neutralization reaction for HCl with NaOH can be represented as: \[ \text{HCl} + \text{NaOH} \rightarrow \text{NaCl} + \text{H}_2\text{O} \] - Since 1 mole of HCl releases 1 mole of H⁺, it will require 1 mole of NaOH to neutralize it. - Therefore, for 1 mole of HCl, we have: \[ X = 1 \] 3. **Neutralization Reaction of H2SO4:** - The neutralization reaction for H2SO4 with NaOH can be represented as: \[ \text{H}_2\text{SO}_4 + 2\text{NaOH} \rightarrow \text{Na}_2\text{SO}_4 + 2\text{H}_2\text{O} \] - Since 1 mole of H2SO4 releases 2 moles of H⁺, it will require 2 moles of NaOH to neutralize it. - Therefore, for 1 mole of H2SO4, we have: \[ Y = 2 \] 4. **Conclusion:** - From the above analysis, we conclude that: - \( X = 1 \) (for HCl) - \( Y = 2 \) (for H2SO4) 5. **Final Statement:** - The relationship between X and Y can be summarized as: \[ Y = 2X \] - Therefore, the correct statement regarding the neutralization of HCl and H2SO4 with NaOH is that 1 mole of HCl requires 1 mole of NaOH (X = 1) and 1 mole of H2SO4 requires 2 moles of NaOH (Y = 2).
