Definition of precipitate for English Language Learners. : 1  to cause (something) to happen quickly or suddenly. : 2  to become separated from a liquid especially by a chemical process. : 3  to cause (something solid) to become separated from a liquid especially by a chemical process.
Precipitates can form when two soluble salts react in solution to form one or more insoluble products - as discussed in the famous example below. The insoluble product separates from the liquid and is called a precipitate. Precipitates can also form when the temperature of a solution is lowered. The lower temperature reduces the solubility of a salt, resulting in its precipitation as a solid.
