Question

Zinc is more reactive than iron what happen if we put a strip of zinc in the copper sulphate solution ?​

Answer 1

Answer:

as zinc is more reactive than copper it will displace copper from its solution and the reaction will be as follows:-

=> zinc (Zn) + copper sulphate solution (Cuso4) ---> zinc sulphate solution (Znso4) + copper (Cu)

Answer 2

Zinc is more reactive than iron and copper because it has the capacity to displace them from their salt solutions.

When a strip of zinc metal is immersed in a copper sulphate solution, the blue colour of the solution fades over time, and a red brown copper coating is developed on the zinc strip.

Reaction: Zn(s)+CuSO 4 (aq)→ZnSO 4​ (aq)+Cu(s)

When a strip of zinc metal is immersed in an iron sulphate solution, it undergoes a displacement reaction, resulting in the formation of zinc sulphate solution and iron metal. Iron metal is displaced from an iron sulphate solution by zinc metal. Because zinc is more reactive than iron, this displacement reaction occurs.
