The correct Answer is:
To solve the question regarding why the solution of blue vitriol (copper sulfate pentahydrate, CuSO4·5H2O) in water is acidic, we can break down the explanation into clear steps:
### Step-by-Step Solution:
1. **Identify Blue Vitriol**:
- Blue vitriol is chemically known as copper sulfate pentahydrate, represented as CuSO4·5H2O.
2. **Dissolution in Water**:
- When blue vitriol is dissolved in water, it dissociates into its constituent ions: Cu²⁺ (copper ions) and SO₄²⁻ (sulfate ions).
3. **Formation of Acid**:
- The copper ions (Cu²⁺) in solution can interact with water molecules. This interaction leads to the formation of sulfuric acid (H₂SO₄) in the solution.
4. **Acidic Nature**:
- The presence of sulfuric acid in the solution is what makes it acidic. Sulfuric acid is a strong acid, and its dissociation in water releases H⁺ ions, which contribute to the acidity of the solution.
5. **Conclusion**:
- Therefore, the solution of blue vitriol in water is acidic primarily because the copper ions react with water to generate sulfuric acid.
### Final Answer:
The solution of blue vitriol in water is acidic because the Cu²⁺ ions react with water to form sulfuric acid (H₂SO₄).
