Consider again the products of the reaction: if either is insoluble, a precipitate will form.

Does insoluble mean precipitate?

In chemistry, a precipitate is an insoluble solid that emerges from a liquid solution. The emergence of the insoluble solid from solution is called precipitation. ... Precipitates can form when two soluble salts react in solution to form one or more insoluble products.

What makes a compound a precipitate?

When two aqueous solutions react, they sometimes form solids in the solution. The solid is called a precipitate. Precipitation reactions occur when the cations of one reactant and the anions of a second reactant found in aqueous solutions combine to form an insoluble ionic solid that we call a precipitate.
