Yellow and Blue Iodine Clock Oscillation Reaction Chemistry Demonstration

This chemistry demonstration kit illustrates the visually striking Briggs-Rauscher oscillating reaction, which demonstrates chemical equilibria. When the prepared yellow solution is mixed on a magnetic stirrer, it cycles repeatedly from yellow to blue and back, providing a memorable classroom experience. The kit includes three 25 ml bottles of 12% hydrogen peroxide, three 25 ml bottles of 0.2M potassium iodate solution, and one 75 ml bottle of 0.03% starch solution. Safety data sheets are included. This kit is designed for laboratory use only.
