Precipitation reaction is a chemical reaction occurring in an aqueous solution where two ionic bonds combine, resulting in the formation of an insoluble salt which are called precipitates.
Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. A precipitate is a solid that forms out of solution.
Example:
The precipitate Silver Chloride is formed when Aqueous silver nitrate (AgNO3) is added to a solution containing potassium chloride (KCl) .
AgNO<sub>3</sub>(aqueous) + KCl(aqueous) —–AgCl(precipitate) + KNO<sub>3</sub>(aqueous)
