Question

Colour of anhydrous \(CuSO_4\) is

• A. White
• B. Blue
• C. Green
• D. Yellow

Answer 1

The Correct Option is A

To solve the problem, we need to identify the color of anhydrous copper sulfate (\( \text{CuSO}_4 \)).

1. Understanding Anhydrous Copper Sulfate:
Anhydrous copper sulfate, \( \text{CuSO}_4 \), is a white, crystalline solid. It is the dry form of copper sulfate and does not contain any water molecules in its structure.

2. Hydrated Copper Sulfate:
On the other hand, hydrated copper sulfate, \( \text{CuSO}_4 \cdot 5\text{H}_2\text{O} \), is blue in color due to the water molecules associated with the copper ions.

3. Conclusion:
The color of anhydrous copper sulfate is white.

Final Answer:
The correct answer is (A) White.
