Question

Student X put fe nailsCU S o4 solution while the student why put CU pieces in fesO4 solution the observation of solution turns green from blue colour observed by which student also write the chemical reaction?​

Answer 1

Remember the reactivity series of metal

s, which says that Iron is more reactive than copper, therefore it can displace copper from its salts (here,copper sulphate).

The displacement reaction taking place can e written as :

Fe + CuSO4(aq) = FeSO4 + Cu

Iron + Copper Sulphate(aq) = Iron sulphate + copper

FeSO4+Cu= no reaction

Answer 2

The observation takes place in student Y's solution.

Fe+CuSO₄--------------------------------------> FeSO₄+Cu
