Answer 1

Answer:

colour of the solution changes from blue colour of copper sulphate changes to light green due to the formation of ferrous sulphate also the iron nails get coated with a reddish brown substance that is copper gets deposited on the surface of the iron nails.this is a displacement reaction in which a more reactive metal(iron) displaces a less reactive metal(copper) from its salt solution.

the below reaction takes place-

CuSO4(aq)+Fe(solid)⇒FeSO4(aq) +Cu(solid)

Answer 2

When iron is added to copper sulphate, it being higher in the activity series reacts and displaces copper from copper sulphate giving ferrous sulphate and copper.
