Product Details

A precipitate forms as a solution is heated, and dissolves again as it cools–opposite of what is typically observed in precipitation reactions. This "discrepant demonstration" is great for introducing the idea that there are exceptions to many rules in chemistry! The solution may be reused many times. Concepts: Exceptions to chemical rules, precipitation, saturation, solubility. Time Required: 15 minutes Chemicals Provided: Calcium acetate saturated solution, 500 mL.
