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.

Explanation

The following is the order iin which the given metals displace each other form the solution of their salts. Mg, Al, Zn, Fe, Cu
Example : `Mg_((S))+Cu_((aq))^(2+) to Mg_((aq))^(2+)+Cu_((S))`

* `E^(Theta)` value increases gradually.
Explanation : The metal which has less `E^(Theta)` value will reduce the metal which has high `E^(Theta)` value and convert metal ions into metal. Mg metal will replace `Cu^(2+)` of solution with `Mg^(2+)`. So, `Mg_((S))` will dissolved and `Cu_((S))` is obtained.
