Question:

Displacement Reactions - Copper Sulphate and Zinc. Can you explain this to me?

I need to know about the displacement reaction between Copper sulphate and zinc. What happens and how it ends up giving copper in the end.

Answer:

When a piece of zinc is dropped into a solution of copper sulphate, the zinc dissolves into the solution and the blue copper sulphate solution slowly becomes paler. At the same time, reddish-brown copper solid (it colud be powder, it could be crystals, I don't know) forms around the piece of zinc. If nothing is in excess, you should see a pile of copper in a colourless solution of zinc sulphate. Zn(s) + CuSO4(aq) -> ZnSO4(aq) + Cu(s)

According to the metallic reactivity series, zinc is above copper, so that it is able to displace it from a compound: Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s) To use a human analogy, suppose Mr. Copper was living in a house married to Ms. Sulfate. One day, there was a knock on the door, and Mr. Zinc stood there, much taller and stronger than Mr. Copper. He threw Mr. Copper out into the cold, and moved in and married Ms. Sulfate. Whether you like the analogy or not, a more reactive metal can displace a less reactive metal from its compound. The same could be said for nonmetals. For example, chlorine can displace bromine from its compound, but not the other way around: Cl2(aq) + 2 NaBr(aq) → 2 NaCl(aq) + Br2(aq)
