Fe(s) +cuso4(blue) (aq) = feso4 ( green ) +cu(s)
When iron nails are placed in copper sulphate solution , wecknow iron is more reactive than copper so iron replace the copper from its sour solution

Answer 2

When iron nail is put inside copper sulphate solution iron being more reactive than copper displaces copper from CuSO4 solution

REACTION: CuSo4+Fe ---> FeSO4+Cu

OBSERVATION:The copper displaced by iron in the reaction is visible as a pink-brown precipitate that usually forms on the unreacted mass of solid iron left over
