An insoluble solid is called a precipitate.

The full definition of a precipitate is an insoluble solid that emerges from a liquid solution. A precipitation reaction occurs when cations and anions in aqueous solution combine to form an ionic solid (the precipitate). The solubility rules determine whether or not a precipitate will form. The solubility rules are as follows: 

1. All compounds of Group IA elements are soluble. 

2. All ammonium salts are soluble. 

3. All nitrate, chlorate, perchlorate, and acetate salts are soluble. 

4. All chloride, bromide, and iodide salts are soluble except for those of Ag+, Pb 2+, and Hg2 ^ 2+. 

5. All sulfate compounds are soluble except for Ba2+, Sr2+, Ca2+, Pb2+, and  Hg2 ^ +2.  Also, Hg2+, Ca2+, and Ag2+ sulfates are only moderately soluble. 

6. All hydroxide compounds are insoluble except for those of Group IA and IIA. 

7. All sulfide compounds are insoluble except for those of Group IA and IIA.

8. All sulfites, carbonates, chromates, and phosphates are insoluble except for those of NH4+ and Group IA.
