Question

which of the following is the correct order in which metals displace each other from the salt solution of their salts?
a) Zn, Al, Mg, Fe, Cu
b) Cu, Fe, Mg, Al, Zn
c) Mg, Al, Zn, Fe, Cu
d) Al, Mg, Fe, Cu, Zn​

Answer 1

Answer:

The order in which the metals displace each other from their salt solutions is Mg>Al>Zn>Fe>Cu.

Answer 2

Answer:

Explanation:

Mg comes before Al, Zn, Fe, and Cu in the reactivity sequence. a reduction in reactivity Reactivity is reduced Mg can so replace Al, and Al can replace Zn, and so on.

In its salt solution, a metal with a higher reducing power pushes out a metal with a lower reducing power.

As a result, Mg can remove Al from its salt solution but Al cannot.

Mg>Al>Zn>Fe>Cu is the order in which the metals are removed from their salt solutions.

Because a metal with a lower electrode potential acts as a more powerful reducer. All of the given metals can be replaced by Mg, while Al can replace all metals barring Mg. Except for Mg and Al, Zn can replace all metals. Only Cu can be moved by Fe. Mg, Al, Zn, Fe, and Cu are the elements that they can push out of their salt solutions in that order.

Hence the correct order in which metals displace each other from the salt solution of their salts is Mg, Al, Zn, Fe, Cu.
