Copper metal can displace magnesium sulphate to give copper sulphate and magnesium.

Answer

To solve the question, we need to analyze the given statement about the displacement reaction between copper metal and magnesium sulfate.

### Step-by-Step Solution:

1. **Understanding the Reaction**: The statement claims that copper metal can displace magnesium sulfate to produce copper sulfate and magnesium. The reaction can be represented as:
\[ \text{Cu} + \text{MgSO}_4 \rightarrow \text{CuSO}_4 + \text{Mg} \]

2. **Identifying Reactivity**: To determine if this reaction can occur, we need to consider the reactivity of the metals involved. In the reactivity series of metals, more reactive metals can displace less reactive metals from their compounds.

3. **Comparing Reactivity**: In this case, magnesium (Mg) is more reactive than copper (Cu). This means that magnesium can displace copper from its compounds, but copper cannot displace magnesium from magnesium sulfate.

4. **Conclusion**: Since copper is less reactive than magnesium, the proposed reaction will not take place. Therefore, the statement that copper can displace magnesium sulfate is incorrect.

5. **Final Statement**: The correct conclusion is that copper cannot displace magnesium from magnesium sulfate, and thus the reaction does not occur.
