What is exchanged in a double displacement reaction?
Answer and explanation
Correct answer: Ions
In a double displacement reaction, the cations and anions of two compounds exchange partners to form new compounds. Its general form is \(AB + CD \rightarrow AD + CB\). For example, in \(Na_2SO_4 + BaCl_2 \rightarrow BaSO_4 + 2NaCl\), ions are exchanged; heat or colour is not exchanged.
