Question

define precipitate & precipitate reaction​

Answer 1

Answer:

In chemistry, a precipitate is an insoluble solid that emerges from a liquid solution. The emergence of the insoluble solid from solution is called precipitation. Often the precipitate emerges as a suspension. Precipitates can form when two soluble salts react in solution to form one or more insoluble products.

A precipitation reaction occurs when adding lead nitrate to potassium iodine to form lead iodine as yellow precipitate.

Explanation:

Answer 2

Double displacement reaction is otherwise known as precipitation reaction.

Precipitate is a semi - solid substance.

Precipitation is the creation of a solid from a solution. When the reaction occurs in a liquid solution, the solid formed is called the 'precipitate'. The chemical that causes the solid to form is called the 'precipitant'.
