Question

NCERT VIII - Sciences

Give reasons for the following.

(c) Copper cannot displace zinc from its salt solution.

Answer 1

Copper cannot displace zinc from its salt solution because zinc is more reactive than copper. More reactive metal displaces less reactive metal from its salt solution.
CuSO4+Zn⇒ZnSO4+Cu
Zn has displaced copper, but copper cannot do so.

Answer 2

copper cannot displace zinc as it is less reactive than zinc and in Chemistry "a more reactive metal can replace a less reactive metal but a less reactive one cannot replace a more reactive one".copper cannot displace zinc so it is placed below zinc in the reactivity series of metals.....
