Precipitation (chemistry) 沉淀

(重定向自Supernatant)
Chemical Precipitation
Crystals of meso-tetratolylporphyrin from a reflux of propanoic acid precipitate on cooling
Copper from a wire displaces silver in a silver nitrate solution it is dipped into, and solid silver precipitates out.

Precipitation is the creation of a solid from a solution. When the reaction occurs in a liquid solution, the solid formed is called the 'precipitate'. The chemical that causes the solid to form is called the 'precipitant'. Without sufficient force of gravity (settling) to bring the solid particles together, the precipitate remains in suspension. After sedimentation, especially when using a centrifuge to press it into a compact mass, the precipitate may be referred to as a 'pellet'. The precipitate-free liquid remaining above the solid is called the 'supernate' or 'supernatant'. Powders derived from precipitation have also historically been known as 'flowers'.
