In which type of reaction do the ions of two compounds exchange with each other?
Answer and explanation
Correct answer: Double displacement reaction
In a double displacement reaction, the cations and anions of two compounds exchange partners. Its general form is \(AB + CD \rightarrow AD + CB\). For example, in \(Na_2SO_4 + BaCl_2 \rightarrow BaSO_4 + 2NaCl\), the ions exchange partners. In contrast, a combination reaction generally forms one product from reactants rather than exchanging ions.
