When aqueous solutions of two ionic compounds are mixed, an insoluble solid forms. This is an example of which type of reaction?
Answer and explanation
Correct answer: Double displacement reaction with precipitation
In a double displacement reaction, ions from two ionic compounds exchange partners. If one of the products is insoluble in water, it separates as a solid precipitate: \(AB(aq)+CD(aq)\rightarrow AD(s)+CB(aq)\). Therefore, this is a double displacement reaction with precipitation. In contrast, a single displacement reaction usually involves an element replacing another element from a compound.
