Question

explain double displacement reaction with an example​

Answer 1

Answer:

Double displacement reactions take place mostly in aqueous solutions wherein the ions precipitate and exchange of ions takes place. For example, when a solution of barium chloride is mixed with sodium sulphate, a white precipitate of barium sulphate is formed rapidly. These reactions are ionic in nature.

Answer 2

A reaction in which ions are exchanged between the two reactant compounds is called double displacement reaction.

For example : BaCl2(aq) + Na2SO4(aq) → BaSO4(s) + 2 NaCl(aq)
