It is an insoluble compound either reacting two salts or changing the temperature to affect the solubility of the compound.

The name given to the solid that is formed as a result of a precipitation reaction.

In chemistry, a precipitate is a substance that forms out of another substance - usually a solid that precipitates out of a liquid

It forms when an insoluble compound in a solution that contains a particular cation (a positively charged ion) and it is mixed with another solution containing a particular anion (a negatively charged ion). The solid that separates is called a precipitate.
