Question

What is a chemical displacement reaction? Mention the condition required for it.​

Answer 1

Answer:

Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Example : Reaction of iron nails with copper sulphate solution

Answer 2

Answer:

When a more reactive element displaces less reactive element from its compound, it is called displacement reaction.

This reaction is of 2 types -

1. Single displacement - It is a type of chemical reaction where an elements react with a compound and takes place of another element in that compound. Example -

Zn(s) + CuSO₄(aq.) →  ZnSO₄(aq.) + Cu(s)

Zinc + Copper Sulphate → Zinc Sulphate + Copper

2. Double Displacement - The reaction in which two different ions or groups of atoms in the reactant molecules are displaced by each other. In this a precipitate is also formed in some situations. Example -

Na₂SO₄(aq.) + BaCl₂(aq.) →  BaSO₄ ↓  +  2NaCl(aq.)

sodium sulphate + barium chloride →

         barium sulhate + sodium chloride
