Question

what is precipitation reaction write any three examples​

Answer 1

Answer:

A precipitation reaction is a type of chemical reaction in which two soluble salts in aqueous solution combine and one of the products is an insoluble salt called a precipitate. Note that not all ionic compounds react to form precipitates.

Explanation:

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

2KOH(aqueous) + CaCl2(aqueous)—-Ca(OH)2(aqueous) + 2KCl(aqueous)

AgNO3(aqueous) + NaCl(aqueous) —- AgCl↓ + NaNO3 (aqueous)

Mg(OH)2(s) + 2HCl (aqueous) ——— MgCl2(aqueous) + 2H2O(l)

Answer 2

ANSWER

Precipitation is a type of displacement reaction in which one the products is formed in the solid state.

• The reaction between silver nitrate and potassium chloride is a precipitation reaction because solid silver chloride is formed as a product.
• Mixing silver nitrate and sodium chloride in water will cause silver chloride to precipitate out of solution as a solid. In this example, the precipitate is silver chloride.
• when a solution of iron chloride and ammonium hydroxide are mixed, a brown precipitate of iron hydroxide is formed.
