Difference Between Double Displacement and Double Decomposition Reaction l Double Displacement vs Double Decomposition Reaction


The key difference between double displacement and double decomposition reaction is that the double displacement reactions are chemical reactions in which the components of two reactants replace each other whereas the double decomposition reactions is a form of double displacement reactions in which one or more reactants does not dissolve in the solvent.

Both terms “double displacement” and “double decomposition” reactions explain the same type of chemical reactions, except, the “double decomposition” is a much older term. Therefore, this older term has been largely replaced by the new term, “double displacement” because this term explains the actual idea of the reaction; a displacement. Moreover, we used the older term when one or more reactants does not dissolve in the solvent.

What is Double Displacement Reaction?

Double displacement reactions are a type of chemical reactions in which the components of two reactants replace each other to form new products. In these reactions, the cation and anions tend to undergo this displacement. Typically, the end product of these reactions is a precipitate. Therefore, the end product is entirely different from the reactants.
