What do you mean by precipitation reaction explain by giving examples

A reaction in which an insoluble solid (called precipitate) is formed is called a precipitation reaction. Example: Na 2CO 3(aq)+ CaCl 2(aq) → CaCO 3(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.

A precipitate reaction means that during the reaction, solids form from an aqueous solution. Also, precipitation reactions occur when cations and anions in aqueous solution combine. Here are some examples, Here you can see that lead(II) cations and iodide anions are the products of the aqueous solution. Looking at the solubility chart, you can see that lead(II) cations and iodide anions do in fact make a solid and also that the sodium cations and nitrate anions are aqueous (as sodium nitrate is soluble).

Note that not all ionic compounds react to form precipitates. Also, a precipitate may form under certain conditions, but not others. For example, changes in temperature and pH can affect whether or not a precipitation reaction will occur. Generally, increasing temperature of a solution increases the solubility of the ionic compounds, improving the likelihood of precipitate formation. The concentration of the reactants is also an important factor. Precipitation reactions are usually single replacement reactions or double replacement reactions. In a double replacement reaction, both ionic reactants dissociate in water and their ions bonds with the respective cation or anion from the other reactant (switch partners). In order for a double replacement reaction to be a precipitation reaction, one of the resulting products must be insoluble in aqueous solution. In a single replacement reaction, an ionic compound dissociates and either its cation or anion bonds with another ion in solution to form an insoluble product.
