Arrange the following metals in the order in which they displace each other from the solution of their salts: $Al$,$Cu$,$Fe$,$Mg$,and $Zn$.
(N/A) metal with a stronger reducing power displaces a metal with a weaker reducing power from its salt solution.
The order of increasing reducing power (based on standard electrode potentials) for the given metals is $Cu < Fe < Zn < Al < Mg$.
Therefore,a metal higher in this series can displace any metal lower than it from its salt solution.
Thus,the order in which the metals can displace each other is $Mg > Al > Zn > Fe > Cu$.
