Surprise your students with the Now You See It! Now You Don't! An Oscillating Chemical Demonstration—ChemTopic™ Lab Activity. Add white solids to a colorless solution, and it quickly changes to orange. Less than a minute later, it’s back to colorless. It continues to oscillate between colorless and orange every 30 seconds for half an hour. Use these surprising results to help students visualize the abstract reaction mechanism. Available as part of the Kinetics—ChemTopic™ Labs digital collection. Click the Price link for digital collection pricing.
