Question

What is a precipitate? And what is precipitation reaction? Give an example?

Answer 1

-Chemical reaction occurring in aqueous solutions where two ionic bonds combine forming up insoluble salts

example AgNO3(aqueous) + KCl(aqueous) —–AgCl(precipitate) + KNO3(aqueous)

Answer 2

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.
