The correct Answer is:
To solve the question regarding which compounds will not react with concentrated sulfuric acid (H₂SO₄) to produce a gas, we will analyze each option provided: zinc sulfate, barium phosphate, magnesium borate, and sodium oxalate. ### Step-by-step Solution: 1. **Understanding the Reactivity of Concentrated H₂SO₄:** Concentrated sulfuric acid is a strong dehydrating agent and can react with certain salts to produce gases. However, it does not react with all salts. 2. **Analyzing Each Compound:** - **Zinc Sulfate (ZnSO₄):** Concentrated H₂SO₄ does not react with zinc sulfate to produce any gas. The sulfate ion (SO₄²⁻) is stable in the presence of concentrated sulfuric acid. - **Barium Phosphate (Ba₃(PO₄)₂):** Similar to zinc sulfate, barium phosphate does not react with concentrated H₂SO₄ to produce any gas. The phosphate ion (PO₄³⁻) is also stable and does not release any gas upon reaction with concentrated sulfuric acid. - **Magnesium Borate (Mg(BO₂)₂):** Concentrated H₂SO₄ does not react with magnesium borate to produce any gas. The borate ion (BO₃³⁻) is stable in this context as well. - **Sodium Oxalate (Na₂C₂O₄):** This compound does react with concentrated sulfuric acid. The reaction produces sodium sulfate (Na₂SO₄) and oxalic acid (H₂C₂O₄). Upon heating, oxalic acid decomposes to release carbon dioxide (CO₂) and carbon monoxide (CO) gases. 3. **Conclusion:** From the analysis, we can conclude that concentrated sulfuric acid will not produce gas with zinc sulfate, barium phosphate, and magnesium borate. The only compound that does produce gas is sodium oxalate. ### Final Answer: The compounds that will not give any gas with concentrated H₂SO₄ are: - Zinc Sulfate (ZnSO₄) - Barium Phosphate (Ba₃(PO₄)₂) - Magnesium Borate (Mg(BO₂)₂)
