An insoluble substance separated from a solution in a concrete state by the action of some reagent added to the solution, or of some force, such as heat or cold. The precipitate may fall to the bottom (whence the name), may be diffused through the solution, or may float at or near the surface. [1913 Webster]

{White precipitate} (Old Chem.) (a) A heavy white amorphous powder ({NH2.HgCl}) obtained by adding ammonia to a solution of mercuric chloride or corrosive sublimate; -- formerly called also {infusible white precipitate}, and now {amido-mercuric chloride}.
