What mainly happens in a double displacement reaction?
Answer and explanation
Correct answer: Exchange of ions between two compounds
In a double displacement reaction, the cations and anions of two compounds exchange partners to form two 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. Option C describes a single displacement reaction, in which one element replaces another element in a compound.
