Question:

What is a precipitation test?

Using Precipitations:

Precipitations deal with solubility of compounds in a given solvent. Compounds have specific requirements needed in order for them to dissolve in a solvent. For instance, an ionic or polar covalent compound are more soluble in a polar solvent rather than nonpolar solvent. On the opposite side, a nonpolar covalent compound is not very soluble in a polar solvent. Using an understanding of what is an is not soluble in various solvents allows us to use precipitation as a test for certain types of chemical compounds or reactions.
