Given reasons for each of the following.
Iron can displace copper from copper sulphate solution, but copper cannot displace iron from iron sulphate.

Explanation

**Step-by-Step Solution:**

1. **Understanding Displacement Reactions**: A displacement reaction occurs when a more reactive metal displaces a less reactive metal from its compound. In this case, we are looking at iron (Fe) and copper (Cu) in their respective sulfate solutions.

2. **Iron Displacing Copper**: When iron is added to copper sulfate (CuSO₄) solution, a reaction occurs:
\[ \text{Fe} + \text{CuSO}_4 \rightarrow \text{FeSO}_4 + \text{Cu} \]
