Answer 1

$\huge{\underline{\red{\mathfrak{♡Answer♡}}}}$

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.

Answer 2

Answer:

When during a chemical reaction, an insoluble solid product is formed which can be separated from the solution by filtration, then the solid product is known as precipitate and the reaction is known as precipitation reaction. For example, when a solution of sodium chloride is added to a solution of silver nitrate, then a white precipitate of silver chloride is formed.

NaCl (aq) + AgNO3 (aq) → NaNO3 (aq) + AgCl
