What do you mean by a precipitation reaction? Explain by giving examples.

Dear Student

A reaction in which an insoluble solid (called precipitate) is formed is called a precipitation reaction.For Example:
Na2CO3(aq) + CaCl2(aq) → CaCO3(s) + 2NaCl (aq)
Sodium Carbonate + Calcium Chloride → Calcium Carbonate + Sodium Chloride
In this reaction, calcium carbonate is obtained as a precipitate. Hence, it is a precipitation reaction

Thanks
