Arrange the following metals in the order in which they displace each

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.
Answer» Solution :`E^(@)Al^(+3)//Al=-1.66"volt"` `E^(@)Cu^(+2)//Cu=+0.34"volt"` `E^(@)FE^(+2)//Fe=-0.44"volt"` `E^(@)Mg^(+2)//Mg=-2.36"volt"` `E^(@)Zn^(+2)//Zn=-0.76"volt"` Reduction potential of metal is more positive then it occurs as STRONG reducing agent. Therefore Mg displaces all the other metals. Al displaces all the other atom in aqueous medium EXCEPT Mg. Zn displaces all the other ATOMS in aqueous medium except Mg and Al. Fe displaces only Cu.
