Question

An element ?X? displaces iron from the aqueous solution of iron
sulphate List your observations if the element ?X? is treated with
the
aqueous solutions of copper sulphate, zinc sulphate and silver
nitrate Based on the observations arrange X, Zn, Cu and Ag in
increasing order of their reactivities

Dear student,

The element X is Magnesium, as magnesiumis more reactive from iron & hence, it displaces iron from the aqueous solution of iron
sulphate.

Observations:

Magnesium with copper sulphate: Mg + CuS

O_{4}

--> MgS

O_{4}

+Cu
Magnesium with zinc sulphate: Mg+ ZnS

O_{4}

--> MgS

O_{4}

+Zn
Magnesium with silver nitrate: Mg + 2AgN

O_{3}

-->Mg(N

O_{3}

)_{2}

+2Ag.

Increasing order of their reactivities:

Ag<Cu<Fe<Zn<Mg
