Question

What happens when copper rod is dipped in iron sulphate solution?

Answer 1

When iron rod is kept dipped in copper sulphate solution for sometimes a brown coating is formed on the solution on the iron rod. this happens, according to reactivity series we know that iron is more reactive than copper so iron displaces copper from copper sulphate and forms iron sulphate.

Answer 2

When a copper rod is dipped in iron sulfate solution no reaction will occur.

• Iron is more reactive than copper.
• Copper has a higher (greater) reduction potential than iron, according to the electrochemical series.
• As a result, the copper's high reduction potential value prevents it from displacing the iron from its salt solution.
• When a copper rod is dipped in an iron sulfate solution, there is no reaction.

• As a result, Cu will not displace iron from iron sulfate, and hence no reaction will occur.
