The gaseous product of the reaction between Sn and conc. H2SO4 is: — p Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Concentrated sulfuric acid (H2SO4) acts as a powerful oxidizing agent rather than a typical acid. Step 2: When reacted with tin (Sn), Sn is oxidized to Sn4+ while H2SO4 is reduced to sulfur dioxide (SO2) gas. Step 3: The balanced chemical equation is Sn + 4H2SO4 -> Sn(SO4)2 + 2SO2 + 4H2O, meaning the expected gaseous product is SO2 (option b).
