Question

Name the reaction in which precipitate is formed.

Answer 1

Precipitation reaction:

1. Two soluble salts in an aqueous solution are combined in this reaction, and then they react, resulting in the creation of two products., one of which is soluble and the other not, the non-soluble product is given the name precipitate.
2. Double displacement reactions are another name for these reactions. The commonly known precipitation reaction is that of silver nitrate and potassium chloride, this produces potassium nitrate soluble in nature and silver chloride, which is a solid residue called a precipitate.$\underset{\mathrm{Silver}\mathrm{nitrate}}{{\mathrm{AgNO}}_3\left(\mathrm{aq}\right)}+\underset{\mathrm{Potassium}\mathrm{chloride}}{\mathrm{KCl}\left(\mathrm{aq}\right)}\to \underset{\mathrm{Silver}\mathrm{chloride}\left(\mathrm{Precipitate}\right)}{\mathrm{AgCl}}+\underset{\mathrm{Potassium}\mathrm{nitrate}}{{\mathrm{KNO}}_3}$
3. They are also known as ionic reactions because they include the exchange of ions, which results in the production of new products.
4. It is also used to treat wastewater that contains heavy metals in the form of hydroxide and sulfide compounds.

Therefore, Precipitation reactions or Double displacement are reactions in which precipitate is formed.
