Usually, a double displacement reaction results in precipitate formation. Define double displacement. Double Displacement: Also known as double replacement; Usually occurs between two ionic compounds, which then in turn create two more ionic compounds. Double displacement reactions generally take place in aqueous solutions in which the ions precipitate and there is an exchange of ions. Double displacement reactions are those in which the reactant compounds exchange positive ions with each other to form new compounds. A double replacement reaction is a type of chemical reaction that occurs when two reactants exchange cations or anions to yield two new products. The overall pattern of a double replacement reaction looks like this: Double replacement reactions—also called double displacement, exchange, or metathesis reactions—occur when parts of two ionic compounds are exchanged, making two new compounds. This ScienceStruck post explains the concept of double displacement reaction in chemistry along with a few examples. A double displacement reaction is a type of chemical reaction in which the reactant ions exchange places to form new products. double displacement synonyms, double displacement pronunciation, double displacement translation, English dictionary definition of double displacement. For example, on mixing a solution of barium chloride with sodium sulphate, a white precipitate of barium sulphate is immediately formed.

The chemical bonds between the reactants may be either covalent or ionic. Double replacement reactions are also called double replacement reactions, double displacement reactions, or metathesis reactions. double displacement definition: nounA chemical reaction between two compounds in which the first and second parts of one reactant are united, respectively, with the second and first parts of the other reactant.
