The scene that best represents the resulting mixture is to be identified. Concept introduction: Precipitation reaction involves the reaction of two soluble ionic compounds to form an insoluble product. The insoluble product is known as precipitate. The reason for the precipitation reaction to occur is the formation of product that is insoluble in nature. Ionic compounds are the compounds that are composed of charged ions. There are held together by electrostatic forces. These compounds dissociate into ions when dissolved in water.
