Statement I : The blue colour of copper sulphate crystal disappers when it is heated strongly.
Statement II : Due to heated , water of crystallization of crystal is lost .

Options

A. Both the statements individually true and Statement II is the correct explanation of Statement I.
B. Both the statements are individually true but Statement II is not correct explanation of Statement I.
C. Statement I is true but Statement II is false .
D. Statement I is false but Statement II is true .

Explanation

To analyze the statements provided in the question, we will break down the concepts involved and verify the truthfulness of each statement step by step.

### Step 1: Understanding Copper Sulfate Crystals
Copper sulfate crystals, specifically copper(II) sulfate pentahydrate (CuSO₄·5H₂O), are blue in color due to the presence of water of crystallization. The water molecules are coordinated to the copper ions in the crystal lattice.

### Step 2: Heating Copper Sulfate Crystals
When copper sulfate pentahydrate is heated strongly, it undergoes a thermal decomposition reaction. The heat causes the water of crystallization to evaporate.

### Step 3: Observing the Color Change
As the water is lost during heating, the blue color of the copper sulfate crystals disappears. The resulting product is anhydrous copper sulfate (CuSO₄), which is white in color.

### Step 4: Evaluating Statement I
- **Statement I**: "The blue color of copper sulfate crystal disappears when it is heated strongly."
- This statement is **True** because the loss of water leads to the disappearance of the blue color.

### Step 5: Evaluating Statement II
- **Statement II**: "Due to heating, water of crystallization of crystal is lost."
- This statement is also **True** because the process of heating causes the water molecules associated with the copper sulfate to evaporate.

### Conclusion
Both statements are true. Therefore, the correct conclusion is that both Statement I and Statement II are accurate.

### Final Answer:
- Statement I is True.
- Statement II is True.
