Explain the following:
Blue colour of solid copper sulphate disappears when concentrated sulphuric acid is added to it. 

Explanation

To explain why the blue color of solid copper sulfate disappears when concentrated sulfuric acid is added, we can break it down into the following steps:

### Step 1: Understanding Copper Sulfate
- Copper sulfate (CuSO₄) exists in two forms: hydrated and anhydrous. The hydrated form, known as copper(II) sulfate pentahydrate (CuSO₄·5H₂O), has a characteristic blue color due to the presence of water molecules in its crystal structure.

### Step 2: Role of Concentrated Sulfuric Acid
- Concentrated sulfuric acid (H₂SO₄) is known to be a strong dehydrating agent. This means it has the ability to remove water from other substances.
