Why sulphuric acid is not used as a drying agent in the preparation of hydrogen ?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Role of a Drying Agent:**
A drying agent is a substance that removes water from a solution or gas. In the preparation of hydrogen, a drying agent is used to ensure that the hydrogen gas collected is free from moisture.

2. **Identifying the Reaction:**
When hydrogen gas (H₂) is produced, it is often generated through the reaction of an acid with a metal. If sulfuric acid (H₂SO₄) is used in this process, it can react with hydrogen.
