Answer:
Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. A precipitate is a solid that forms out of solution.
A common example is that of the mixing of two clear solutions: Silver nitrate (AgNO
3
) and sodium chloride (NaCl):
AgNO
3
(aq)+NaCl(aq)→AgCl(s)↓+NaNO
3
(aq)
The precipitate forms because the solid (AgCl) is insoluble in water.

Answer:
A precipitation reaction refers to the formation of an insoluble salt when two solutions containing soluble salts are combined. The insoluble salt that falls out of solution is known as the precipitate, hence the reaction's name. Precipitation reactions can help determine the presence of various ions in solution.
