Is matter created or destroyed during a chemical reaction? This experiment for grades 8-12 uses sodium hydroxide, copper sulfate, household ammonia, and sodium carbonate (washing soda). Students prepare two solutions, add sodium hydroxide to each solution and immediately weigh each. The solutions are weighed again after the chemical reaction occurs. If done correctly, the experiment verifies the Law of Conservation of Matter.
CAUTION: Though these substances are easy to acquire, caution is advised. Sodium hydroxide is caustic, so students must wear gloves. Copper sulfate can cause eye irritation/infection, so protective goggles are recommended. The Science House is a project based at North Carolina State University. It sponsors teacher training programs, curriculum development, web-based experiments for use in K-12 classrooms, long-term loans of laboratory equipment, summer student research programs, and community outreach.
