Question 35
Which of the following can undergo a chemical reaction?
(a) ${MgSO}_{4} + Fe$
(b) ${ZnSO}_{4} + Fe$
(c) ${MgSO}_{4} + Pb$
(d) ${CuSO}_{4} + Fe$

Solution

Option (d) is correct.

Iron, ( $Fe$ ) being more reactive than copper, will displace it from its solution, to form iron sulphate solution.

${CuSO}_{4} (aq) + Fe(s) \to {FeSO}_{4} (aq) + Cu(s)$

In other cases, the solutions are of more reactive metal.
