Question

write experimental procedure to prove chemical dicplacement reaction

Answer 1

A chemical Displacement reaction is a reaction that occurs in a compound in which the less reactive element is displaced by the more reactive element.

An example of chemical displacement reaction is - displacement reaction of magnesium and copper sulfate.

When a piece of Magnesium metal strip is kept in a solution of copper sulfate, then the blue color of the solution disappears and the magnesium metal strip becomes brown. This is because of the deposition of the displaced copper from the solution onto the metal strip.

Since the reactivity of magnesium is more than copper, it displaces copper from the copper sulfate solution.

Mg (s) + CuSO₄ (aq) → MgSO₄ (aq) + Cu (s)

Answer 2

Displacement reactions are those reactions in which strong reactive elements replaces the weak element in a compound. The strong one usually comes from the outside and take place the elements of the compound.
For example, when Iron is reacted with copper sulfate it produced the iron sulfate as the iron replace the copper in the copper sulfate and let it free.
Fe +CuSO4 ⇒FeSO4 + Cu 

This is because the reactivity of iron is more than the copper hence ended up replacing it.
