What is a Double Displacement Reaction?

The double displacement reactive is a form of reaction where two compounds react to the exchange of ions in order to form two new compounds. In this reaction, the positive ions are the partner of negative ions. It is expected that the ionic compounds that get dissolved in water are the ones where the double displacement reaction takes place. Here is the reaction to represent the double displacement Reaction.

In a double displacement reaction, the atoms belonging to the two different compounds switch their places. The reactants are two compounds whereas, the products are two different compounds. Such as-

Fe₂O₃ + 6HCl → 2FeCl + 3H₂O

The Double displacement reactions can be further classified as precipitation and neutralization reactions.
