Recovering Copper from CuSO4 Solution
CuSO4 solution contains copper ions and sulfate ions. To recover copper from this solution, a metal with a higher reduction potential than copper is required. The metal will displace copper ions from the solution and form a solid metal precipitate.
Options:
a) Na (Sodium)
- Sodium has a lower reduction potential than copper.
- Sodium cannot displace copper from the solution.
- Therefore, option 'A' is incorrect.
b) Ag (Silver)
- Silver has a lower reduction potential than copper.
- Silver cannot displace copper from the solution.
- Therefore, option 'B' is incorrect.
c) Hg (Mercury)
- Mercury has a lower reduction potential than copper.
- Mercury cannot displace copper from the solution.
- Therefore, option 'C' is incorrect.
d) Fe (Iron)
- Iron has a higher reduction potential than copper.
- Iron can displace copper from the solution.
- Therefore, option 'D' is correct.
Conclusion:
To recover copper from a CuSO4 solution, a metal with a higher reduction potential than copper is required. Iron is the metal that can displace copper from the solution and form a solid metal precipitate.

From a solution of CuSO₄, the metal used to recover copper isa)N...
To recover copper from a solution of CuSO₄ (copper sulfate), the metal used is iron (Fe). This process is known as displacement reaction or single displacement reaction. In this reaction, iron (which is more reactive than copper) displaces copper from its solution, and copper metal is deposited.
The reaction is:
- Na (Sodium) is highly reactive and would not be used in this reaction for recovering copper.
- Ag (Silver) and Hg (Mercury) are less reactive than copper and cannot displace copper from its solution.
Thus, the correct metal to recover copper from a solution of CuSO₄ is iron (Fe).
Therefore, the correct answer is Option D: Fe.
