ANSWER

When zinc reacts with a solution of copper sulphate, we obtain Zinc Sulphate and Copper.

Zn + CuSO

4

→ ZnSO

4

+ Cu

Zinc lies above Copper in the activity series.The activity series of metals refers to the list of metals ranked in the decreasing order of their reactivity in order to displace Hydrogen gas from water or acid solutions

Iron metal is more reactive than copper. Therefore, it can displace copper from copper sulphate solution. Cu is less reactive than iron, therefore, cannot replace iron from iron sulphate.

Fe + CuSO

4

→ FeSO

4

+ Cu

Answer 2

Answer:

on adding zinc to CuSO

4

solution, zinc displaces copper from copper sulphate & forms zinc sulphate solution because zinc is more reactive metal which displaces less reactive metal from its solution.

This is indicated by a colour change from blue to colourless.

CuSO

4

solution has a blue colour while ZnSO

4

solution is colourless.

Zn+CuSO

4

→ZnSO

+Cu
