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

Q.1: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

Solution:

A metal is able to displace other metal from their salt solution if the former metal has lower electrode potential

 We get the following order when put the metal in order of their increasing electrode potential

Mg(–2.37), Al(–1.66) , Zn (–0.76), Fe(–0.44), Cu(0.34)
