    • n precipitate In Chem., any substance which, having been dissolved in a fluid, falls to the bottom of the vessel on the addition of some other substance capable of producing decomposition of the compound. The term is generally applied when the separation takes place in a flocculent or pulverulent form, in opposition to crystallization, which implies a like separation in an angular form. But chemists call a mass of crystals a precipitate when they subside so suddenly that their proper crystalline shape cannot be distinguished by the naked eye. Substances which fall or settle down, as earthy matter in water, are called sediments, the operating cause being mechanical and not chemical.
    • n precipitate Fusible white precipitate, colorless crystals, soluble in water (probably of the composition NHg2C1.3NH4Cl), which melt and then decompose on being heated: produced by boiling the infusible white precipitate with a solution of ammonium chlorid.
    • n precipitate An abbreviated term sometimes used to signify the bright yellow precipitate of ammonium phosphomolybdate frequently obtained in analysis as a proof of the presence of, or as the means of quantitatively determining, phosphorus or the radical of phosphoric acid and phosphates.
