Beyond Benign


Chemical or Physical?

This lab replaces traditional reactions involving chemicals such as copper(II) chloride, 6M hydrochloric acid, potassium hydroxide, and copper sulfate. The goal is to use observations of different types of reactions to discover common threads, ultimately leading to conclusions regarding evidence of chemical reactions. Students will ultimately learn the difference between chemical and physical changes and dispel common misconceptions; i.e. boiling water is not a chemical reaction.
