Why do mean by a precipitation reaction?explain giving examples. |
|
Answer» 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.In a chemical reaction down arrow head is symbol of precipitation (↓)FeCl3 (aq) + 3NH4OH → Fe(OH)3 (s) ↓ + 3NH4Cl A reaction in which precipitates are formed is called a precipitation reaction. Precipitates are insoluble solids in a chemical reaction which emerges from a liquid solution. For eg......Na2SO4 +BaCl2 -------> BaSO4 + NaCl ~~~Here white precipitates are formed of BaSO4.....Hope it helps??
