There is no change in the mass of `H_(2)SO_(4)` during the elestrolysis of water which has been acidified with sulphuric acid . Illustrate giving reasons .

Explanation

To understand why there is no change in the mass of `H₂SO₄` during the electrolysis of water acidified with sulfuric acid, we need to analyze the reactions occurring at the electrodes and the behavior of sulfuric acid in the solution.

### Step-by-Step Solution:

1. **Dissociation of Sulfuric Acid**:
- When sulfuric acid (H₂SO₄) is dissolved in water, it dissociates into hydrogen ions (H⁺) and sulfate ions (SO₄²⁻):
\[
H₂SO₄ \rightarrow 2H^+ + SO₄^{2-}
