A precipitation titration is a titration in which the active components combine to form a sparingly soluble precipitate. The stoichiometric point is reached when the ions have been combined in the ratio of the precipitate's formula. The determination of chloride with silver nitrate, which forms insoluble silver chloride, is a common example.

沉淀滴定是活性组分结合生成难溶沉淀的滴定。当离子按沉淀化学式的比例结合时即达到化学计量点。用硝酸银测定氯离子(生成难溶的氯化银)是常见的例子。
