- a chemical reaction between two compounds where the positive ion of one compound is exchanged with the positive ion of another compound.
- Double displacement reactions generally take place in aqueous solutions in which the ions precipitate and there is an exchange of ions.
- For example, on mixing a solution of barium chloride with sodium sulphate, a white precipitate of barium sulphate is immediately formed.
- These reactions are ionic in nature.
