Precipitation is the process of transforming a dissolved chemical substance into an insoluble solid from a super-saturated solution. When the reaction occurs in a liquid solution, the solid formed is called the precipitate. In case of a chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant.
