Arrange the following metals in the order in which they displace each other from the solution of their salts AI,Cu,Fe,Mg and Zn

Explanation

From the the `E_(AI^(3+)//AI)^(@)=-1.66 v E_(Cu^(2+)//Cu)^(@)=+0.34 V`
`E_(Fe^(2+)//Fe)^(@)=-0.44 V E_(Mg^(2+)//Mg)^(@)=-2.36 v` and `E_(Zn^(2+)//Zn)^(@)=-0.76 V`
since a metal with more -ve electrode potential is a strongr reducing agent than the one haveing less neagtive or +ve electrode potential therefore Mg can displace all the above metals from their aquiesoue solutoin AI can displace all metals except Mg form the aquieoius solution of their salts working on similar lines we can show that zn can displace all metals except Mg and AI from the aqueous solution of their salts while fe can displace only Cu from the aqueous solution of its salts thus the order in which they can displace each other from the solution of their salts is Mg AI ,An Fe Cu
