Text Solution

AI Generated Solution

To understand why sulfuric acid (H₂SO₄) is stronger than sulfurous acid (H₂SO₃), we can follow these steps: ### Step 1: Identify the Chemical Structures - Sulfuric acid has the formula H₂SO₄, while sulfurous acid has the formula H₂SO₃. - The structure of sulfuric acid includes a sulfur atom bonded to four oxygen atoms (two of which are double-bonded and two are single-bonded to hydroxyl groups). - The structure of sulfurous acid has a sulfur atom bonded to three oxygen atoms (one double-bonded and two single-bonded to hydroxyl groups). ### Step 2: Determine the Oxidation States of Sulfur ...
