Double Displacement Reaction:Reactions in which ions are exchanged between two reactants forming new compounds are called double displacement reactions. Example: When solution of barium chloride reacts with the solution of sodium sulphate, white precipitate of barium sulphate is formed along with sodium chloride.A double displacement reaction is a type of chemical reaction in which the reactant ions exchange places to form new products.
