Detailed explanation-1: -Precipitation is the process of formation of an insoluble solid when solutions are mixed. The solid thus formed is called precipitate. Only those compounds form precipitates which are insoluble in water.

Detailed explanation-2: -A precipitate is a solid formed in a chemical reaction that is different from either of the reactants. This can occur when solutions containing ionic compounds are mixed and an insoluble product is formed. The identity of the precipitate can often be determined by examining solubility rules.

Detailed explanation-3: -Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids.

Detailed explanation-4: -A precipitation reaction is one in which dissolved substances react to form one (or more) solid products.

Detailed explanation-5: -Tell students that sometimes when two liquids are mixed, a solid forms. This solid is a new substance, and it’s called a precipitate. Explain that when substances are mixed and a new substance is formed, a chemical reaction has occurred.
