Hey Friend,

When iron fillings are added to copper sulphate, the following reaction takes place...

Fe (s) + CuSO4 (aq) ---> FeSO4 (aq) + Cu (s)

Observation -

Iron fillings acquire a reddish brown colour due to the deposition of copper metal.
The copper sulphate solutions which was blue in colour changes to light green colour due to the formation ferrous sulphate.

Hope it helps!
