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`

Text Solution

Verified by Experts

The correct Answer is:
`underset(E^(Theta)-2.37V)(Mg) gt underset(-1.66V)(Al) gt underset(-0.76V)(Zn) gt underset(-0.44V)(Fe) gt underset(+0.34V)(Cu)`
A metal with lesser `E^(Theta)` value will displace another metal from its solution.
