What is precipitationreactiin |
|
Answer» The chemical reaction in which a white coloured substance which is insoluble in water (precipitate) is formed then it is known as precipitation reaction:Na2SO4(aq) + BaCl2(aq) → BaSO4(s) + 2Nacl(aq)In this reaction Barium sulphate is a white colour precipitate and it is insoluble in water. Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids.For example, sometimes the pipes in our homes get clogged because precipitates of magnesium and calcium oxides have deposited themselves within the pipes. |
