A precipitation reaction occurs when two aqueous solutions react to form an insoluble solid, known as the precipitate. This type of reaction is a double displacement reaction where the ions in solution exchange partners.

Precipitation reactions involve the formation of an insoluble product from soluble reactants.
The general form of a precipitation reaction is AB(aq) + CD(aq) -> AD(s) + CB(aq).
Solubility rules help predict whether a precipitate will form in a given reaction.
Precipitates can be identified by their characteristic colors and physical properties.
These reactions are commonly used in qualitative analysis to identify the presence of specific ions.
