Question

State what would happen if
1.some Zn pieces are placed in blue CuSo4 solution
2.some Cu pieces are placed in green FeSo4 solution
3.an Fe nail is dipped in a solution of CuSo4 for sometime

Answer 1

Heya !!

Here is your answer

____________________________________

1. Zn + CuSO4 ----- ZnSO4 + Cu
Zn replaces copper from its compound, what is a type of displacement reaction.


2. Cu + FeSO4 ----- No reaction
As Fe is more reactive than copper.


3. Fe + CuSO4 ---- FeSO4 + Cu

Answer 2

In first one zinc being more reactive than copper would displace it so u will get Zn + CuSO4---> ZnSO4 + Cu

And In second one nothing will happen as Cu is less reactive than Fe so when Fe is put into blue CuSO4 it will displace copper and hence turn green but here u already have copper into green FeSO4

In third one as I said above iron would displace copper reason being more reactive , so the solution would turn greenish and u can see a layer of rust forming upon iron nail which is the displaced copper
