Give reasons for the following
In the electrolysis of acidified water dilute sulphuric acid is preferred to dilute nitric acid for acidification

Explanation

To answer the question of why dilute sulfuric acid is preferred to dilute nitric acid for the electrolysis of acidified water, we can break down the reasoning into a few key points:

### Step-by-Step Solution:

1. **Formation of Ions**:
- Dilute sulfuric acid (H₂SO₄) dissociates in water to form hydrogen ions (H⁺) and sulfate ions (SO₄²⁻). This dissociation occurs readily, providing a sufficient concentration of ions necessary for the conduction of electricity during electrolysis.
- In contrast, dilute nitric acid (HNO₃) also dissociates to form hydrogen ions (H⁺) and nitrate ions (NO₃⁻), but the extent of dissociation is not as favorable for the electrolysis process.
