Which of the foll A. MgSO4 + Fe
B. ZnSO4 + Fe
C. MgSO4 + Pb
D. CuSO4 + Fe
CuSO4 + Fe can undergo a chemical reaction. As iron metal is more reactive than copper metal, iron displaces copper from copper sulphate solution and forms aqueous iron sulphate (FeSO4) and solid copper (Cu). This a single displacement reaction also known as a substitution reaction. The iron can be solid or aqueous but the copper sulphate must be aqueous in order to facilitate the reaction.
