A precipitation reaction is a chemical reaction that occurs in aqueous solution and form precipitates. Answer (1 of 7): Precipitate is what falls out of a super saturated solution or what remains after a super-saturated solution evaporates. What type of reaction is common to the formation of all precipitates? In a chemical laboratory it usually refers to a solid crystallizing from a liquid solution, but in weather reports it applies to liquid or solid water separating from supersaturated air. The precipitate stays in the solution as a barrier, or it can also be removed from the liquid by using the process of centrifugation, decantation or filtration. Since the precipitate is formed by the exchange of the ions in the aqueous solution, it is also called a double displacement reaction. . The positive ions from the hard water react with the negative ions from the soap to then create the formation of bathtub rings. Give an example of a reaction in which precipitate is formed. 4. 2. A chemical reaction is irreversible, while a physical one is easily reversible. You may want to refer to page 3 of this handout for help identifying colors of precipitates. The formation of bubbles when two liquids are mixed usually indicates that a gas has formed. The apparatus is the calorimeter. Continue on to the next sign.
