Question

explain about precipitation reaction

Answer 1

precipitation reaction is also known as double displacement reaction it involves forming a precipitate and a solution in which the precipitate is not soluble in that particular solution example: reaction between barium chloride and sodium sulphate it forms white precipitate is an example of precipitation reaction another example of precipitation reaction is the reaction between lead nitrate and potassium iodide which forms yellow precipitate lead iodide which is insoluble in potassium nitrate

Answer 2

HEY MATE HERE IS UR ANS.....
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. Because not all aqueous reactions form precipitates, one must consult the solubility rules before determining the state of the products and writing a net ionic equation. The ability to predict these reactions allows scientists to determine which ions are present in a solution, and allows industries to form chemicals by extracting components from these reactions.

Properties of Precipitates
Precipitates are insoluble ionic solid products of a reaction, formed when certain cations and anions combine in an aqueous solution. The determining factors of the formation of a precipitate can vary. Some reactions depend on temperature, such as solutions used for buffers, whereas others are dependent only on solution concentration. The solids produced in precipitate reactions are crystalline solids, and can be suspended throughout the liquid or fall to the bottom of the solution. The remaining fluid is called supernatant liquid. The two components of the mixture (precipitate and supernate) can be separated by various methods, such as filtration, centrifuging, or decanting.
