Question

Give reason why copper cannot displace zinc from its salt solution.

Answer 1

Answer:

copper can't displace zinc from its salt solution because zinc is more reactive than copper

Answer 2

Explanation:

Copper cannot displace zinc from its salt solution because zinc is more reactive metal as compared copper in the Metal Reativity Series. And as we know, more reactive metal displaces less reactive metal from its salt solution. here's an reaction to make things more clear.

CuSO4+Zn⇒ZnSO4+Cu

Zinc has displaced Copper from Copper Sulfate solution to form Zinc Sulfate solution.

But when we try to reverse the process, for example,

ZnSO4+Cu⇒ZnSO4+Cu

We will notice no change.

Thus we can say that Copper, being a low reactive metal, cannot displace it's higher reactive metal like Zinc.
