Why sulphuric acid is stronger than sulphurous acid?

Explanation

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
