When is a chemical reaction considered a double displacement reaction

1.	When is a chemical reaction considered a double displacement reaction ? Explain giving example. State a difference between displacement and double displacement reaction.
Answer» A reaction is considered a double displacement reaction if during the chemical reaction an exchange of ions takes place between two ionic substances. Example: BaCl₂+Na₂SO₄→ BaSO₄+2NaCl ln a displacement reaction, a more reactive element displaces or removes another less reactive element. from its compound e.g. Fe+CuSO₄ → FeSO₄+Cu whereas in a double displacement reaction, the compounds react by exchanging their ions and from two new compounds.

Answer»

A reaction is considered a double displacement reaction if during the chemical reaction an exchange of ions takes place between two ionic substances.

Example: BaCl₂+Na₂SO₄→ BaSO₄+2NaCl

ln a displacement reaction, a more reactive element displaces or removes another less reactive element. from its compound

e.g. Fe+CuSO₄ → FeSO₄+Cu

whereas in a double displacement reaction, the compounds react by exchanging their ions and from two new compounds.
