Question

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

Answer 1

Answer:

Explain by giving examples. When two reactants in solution react and one or more of the products is insoluble or forms a precipitate, the reaction is called a precipitation reaction. For example, when a solution of iron chloride and ammonium hydroxide are mixed, a brown precipitate of iron hydroxide is formed.

Answer 2

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