A precipitation reaction is a type of chemical reaction that occurs when two soluble salts in aqueous solution combine and one of the products is an insoluble solid called a precipitate. The reactants are ions in the solution, and the insoluble product is referred to as the precipitate. Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate/Descriptive_Chemistry/Main_Group_Reactions/Reactions_in_Aqueous_Solutions/Precipitation_Reactions). These reactions are commonly used to help determine what ions are in the solution. A precipitation reaction is a double replacement reaction when the chemical equation in question occurs in aqueous solution and one of the products formed is insoluble/Descriptive_Chemistry/Main_Group_Reactions/Reactions_in_Aqueous_Solutions/Precipitation_Reactions). The onset of nucleation is an important stage of the precipitation process, which involves energy changes depending on the dissolution reaction free energy and the relative surface energy developed between the solid and the solution). If energy changes are not favorable, or without suitable nucleation sites, no precipitation occurs and the solution remains supersaturated).
