Once the precipitate has been recovered, the resulting powder may be called a "flower. A common sedimentation technique is centrifugation. Sedimentation refers to any procedure that separates the precipitate from the liquid portion of the solution, which is called the supernate. If the particle size of the insoluble compound is very small or there is insufficient gravity to draw the solid to the bottom of the container, the precipitate may be evenly distributed throughout the liquid, forming a suspension. Precipitation reactions are useful in determining whether a certain element is present in a solution. The solid that is formed is called the precipitate. A chemical that causes a solid to form in a liquid solution is called a precipitant. Here's how it works: forming a solid from a solution is called precipitation. The terminology can seem a bit confusing. This can happen for a variety of reasons, but a student may have taken the very hot solution and placed it directly on a cold surface to cool (a process called shock cooling) or even plunged the hot solution into an ice bath. They are used for purification, removing or recovering salts, for making pigments, and to identify substances in qualitative analysis. A precipitate is simply a mixture of compounds in the solution that crash out. Commonly used chemical cleaners for membrane systems are given in Table 2.13. Precipitation reactions serve important functions. Chemical cleaning is based on chemical reactions hydrolysis, saponification, solubilisation, dispersion, chelation, and/or peptisation to break down bonds and cohesion forces between the membrane surface and the foulants 32.

The solid that forms via a precipitation reaction is called the precipitate.In order to remove these impurities, precipitate is washed with water as water will wash. To precipitate is to form an insoluble compound, either by decreasing the solubility of a compound or by reacting two salt solutions. Some ions and impurities gets adsorbed on the surface of precipitate.In chemistry, precipitate is both a verb and a noun.
