How are the products identified in a double displacement reaction?
Answer and explanation
Correct answer: By interchange of the cations and anions of two compounds
In a double displacement reaction, the ions of two ionic compounds interchange. In general, \(AB + CD \rightarrow AD + CB\). Therefore, the products are identified by forming the new cation–anion pairs. Option D describes a single displacement reaction, not a double displacement reaction.
