Question

what happens when following metals are added to CuSO4 solution. Write the colour change involved and also write the chemical equation.
(i) Cu
(ii) Al
(iii)Fe
(iv)Zn​

Answer 1

$(i)~\sf CuSO4 + Cu → No \: reaction$

$(ii)~\sf 3CuSO_4 + 2Al → Al_2(SO_4)_3 + 3Cu$

$(iii)~\sf CuSO_4 + Fe → FeSO_4+ Cu$

$(iv) ~\sf CuSO_4 + Zn→ ZnSO_4+Cu$
