A solution of copper sulphate may be kept safely in the container made up of

Options

A. Fe
B. Ag
C. Zn
D. AI

Explanation

To determine the appropriate container for storing a solution of copper sulfate, we need to consider the reactivity of the metals involved and the nature of copper sulfate itself.

### Step-by-step Solution:

1. **Identify the Composition of Copper Sulfate**:
Copper sulfate (CuSO₄) is a salt formed from copper and sulfuric acid. It is commonly encountered in its pentahydrate form (CuSO₄·5H₂O).

2. **Consider the Reactivity of Metals**:
- Copper is a transition metal, and it is relatively unreactive compared to other metals.
- Silver (Ag) is also a noble metal and does not react with copper sulfate.

3. **Select Suitable Materials for the Container**:
- Since copper sulfate does not react with silver, a container made of silver would be safe for storing copper sulfate solution.
- Other materials that are commonly used for chemical storage, such as glass or certain plastics, are also suitable as they do not react with copper sulfate.

4. **Conclusion**:
A solution of copper sulfate may be safely kept in a container made of silver (argentum) or other non-reactive materials like glass.

### Final Answer:
A solution of copper sulfate may be kept safely in a container made up of silver (argentum) or glass.
