Carolina Chemonstrations®: Iodine Clock Reaction Kit

Item # 840325 Exclusive

Timing is everything in this engaging demonstration of the classic iodine clock reaction! Students observe how temperature, concentration, and the addition of a catalyst affect the rate at which a colorless solution changes to a deep blue color. They then model the reaction on a particulate level and calculate the rate of each reaction. This demonstration requires approximately 15 min of prep time and 30 min of classroom time, and materials are sufficient for 5 demonstrations.

  • Introduces chemical reactions and wows students with the wonders of chemistry
  • Helps address advanced chemistry topics such as kinetics, catalysts, and multistep reactions
  • Aligns with AP Chemistry Big Idea 4: Rates of chemical reactions

Timing is everything in this engaging demonstration of the classic iodine clock reaction! After drawing upon prior knowledge to predict what might happen in the demo, students observe how temperature, concentration, and the addition of a catalyst affect the rate at which a colorless solution changes to a deep blue color. They then model the reaction on a particulate level and calculate the rate of each reaction. The activity concludes with students answering big picture questions that connect their learning about reaction kinetics to real-world situations. This demonstration requires approximately 15 min of prep time and 30 min of classroom time, and materials are sufficient for 5 demonstrations.
