When the chemical reaction occur the solid formed is called, precipitate. This can occur when an insoluble substance, the precipitate, is formed in the solution due to a reaction or when the solution has been supersaturated by a compound. The formation of precipitate is a sign of a chemical change. In the most situations, the solid forms out of solute phase, and sink to the bottom of solution(though it will float if it is less dense than the solvent or form suspension). Precipitate:        When the reaction occurs, the solid formed is called precipitate . Precipitant:      The agents which cause precipitation from a s
