- A. Na

- C. Hg
- D. Fe ✓
The answer to the question is: D. Fe
The metal used to recover copper from a solution of copper sulphate is iron (Fe). Iron is commonly used in the process of copper recovery due to its ability to displace copper from its compounds. When iron is added to a solution of copper sulfate, a single displacement reaction occurs, resulting in the formation of iron sulfate and solid copper. The balanced chemical equation for this reaction is:
Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)
In this reaction, iron displaces copper from the copper sulfate solution, leading to the formation of solid copper, which can then be recovered.
