The gas liberated when Sodium Sulphite reacts with dilute sulphuric acid is

Explanation

To determine the gas liberated when sodium sulphite reacts with dilute sulphuric acid, we can follow these steps:

### Step 1: Write the Reactants
The reactants in this reaction are sodium sulphite (Na₂SO₃) and dilute sulphuric acid (H₂SO₄).

### Step 2: Identify the Reaction
