Question

explain why blue colour of copper sulphate solution is discharged on adding iron dealing to it

Answer 1

HELLO!!!

It happens so because Iron is more reactive than copper s it displaces copper from copper sulphate solution. That is:

CuSO₄ + Fe ⇒ FeSO₄ +Cu. It is a displacement reaction where one metal is more reactive than the other and so it displaces the other metal which is less reactive.

Hope you found it Helpful. :) :)
