Arrange the following metals in the order in whiCHM they displace eaCHM other from the solution of their salts. `Al, Cu, Fe, Mg, ` and `Zn`.

Explanation

A metal of stronger reducing power displaces another metal of weaker reducing power from its solution of salt .
The order of the increasing reducing power of the given metals is `Cu lt Fe lt Zn lt Al lt Mg.` ltbgt Hence , we can say that Mg can displace Al from its salt solution, but Al cannot displace Mg.
Thus , the order in which the given metals displace each other from the solution of their salts is given below :
`Mg gt Al gt Zn gt Fe gt Cu`
