Let’s Review!

Chemical changes are reactions in which molecular change takes place. Molecules change into completely different molecules.

These changes can be signified by changes in color, odor and/or temperature. Chemical changes can also produce new gases or solids. (The bubbles from your pH experiment.)
They are rarely reversible.

Physical changes are changes in shape, size or state of matter that do not change molecular structure. They are often reversible.
