Sulphuric acid has great affinity for water because it

Options

A. Decomposes water
B. Forms hydrate with water
C. Hydrolyse the acid
D. Decomposes the acid

Answer

**Step-by-Step Solution:**

1. **Understanding Sulfuric Acid (H₂SO₄):**
Sulfuric acid is a strong acid and is known for its ability to interact with water.

2. **Affinity for Water:**
The term "affinity for water" means that sulfuric acid has a strong tendency to attract and combine with water molecules.

3. **Hygroscopic Nature:**
Sulfuric acid is hygroscopic, which means it can absorb moisture from the environment. This property allows it to take up water without necessarily dissolving in it.

4. **Formation of Hydrates:**
When sulfuric acid comes into contact with water, it can form hydrates. This means that it can incorporate water molecules into its structure, leading to the formation of compounds that contain water.

5. **Decomposition and Hydrolysis:**
The options provided in the question include the decomposition of water and hydrolysis of the acid. However, these processes do not accurately describe the primary reason for sulfuric acid's affinity for water.

6. **Conclusion:**
The correct reason for sulfuric acid's great affinity for water is that it forms hydrates with water and absorbs water without dissolving in it.

**Final Answer:**
Sulfuric acid has a great affinity for water because it forms hydrates with water and absorbs water without dissolving in it.
