The Iodine clock experiment is one of the most enduring chemistry experiments because of the dramatic, visual transformation of the solutions! We take this chemistry experiment and then take it a step further by comparing the speed of the colour change to the temperature of the solution! The Iodine clock is simple and easy to do at home. What is an iodine clock reaction? You will need Water, Iodine, Hydrogen Peroxide (H202) Corn Starch and a Vitamin C Tablet. This is such a cool colour changing experiment!
00:00 Intro to the Iodine clock and Destructive Creativity.
01:04 What are we doing with the iodine clock?
01:33 Making Solution A of the Iodine clock experiment
02:50 Making Solution B of the Iodine clock experiment
03:44 Explanation of what is happening and showing the reaction
04:36 This is SO COOL!
05:33 Testing the 20 degree Celsius reaction time of the chemical reaction
06:03 Testing the 4 degree Celsius reaction time of the chemical reaction
07:33 Testing the 67 degree Celsius reaction time of the chemical reaction
08:12 Conclusion and result of the science experiment.
