The correct Answer is:
To determine how hydrogen peroxide (H₂O₂) is manufactured these days, we will analyze the provided options step by step. ### Step 1: Analyze the Options We have four options for the manufacturing process of hydrogen peroxide: 1. By the action of hydrogen peroxide on barium oxide. 2. By the action of sulfuric acid on sodium oxide. 3. By electrolysis of 50% H₂SO₄ (sulfuric acid). 4. By burning hydrogen in excess of oxygen. ### Step 2: Evaluate Each Option - **Option 1:** By the action of hydrogen peroxide on barium oxide. - This option is incorrect because it implies that hydrogen peroxide is already present, which does not describe a manufacturing process. - **Option 2:** By the action of sulfuric acid on sodium oxide. - This option is also incorrect. While sulfuric acid is a strong acid, it does not react with sodium oxide to produce hydrogen peroxide. - **Option 3:** By electrolysis of 50% H₂SO₄. - This option is correct. Electrolysis of sulfuric acid leads to the formation of hydrogen peroxide along with sulfuric acid. - **Option 4:** By burning hydrogen in excess of oxygen. - This option is incorrect because burning hydrogen in oxygen produces water (H₂O), not hydrogen peroxide. ### Step 3: Conclusion The correct method for the manufacturing of hydrogen peroxide is **Option 3: By electrolysis of 50% sulfuric acid**. ### Final Answer Hydrogen peroxide (H₂O₂) is manufactured these days by **electrolysis of 50% sulfuric acid (H₂SO₄)**. ---
