WebThis guided-inquiry activity allows students the opportunity to observe the iodine clock reaction, analyze how the concentration of potassium iodate influences the rate of the reaction, and then predict the amount of potassium iodate needed to make the clock “ring” in 25 seconds and verify the accuracy of their prediction. WebThe iodine clock reaction is a classical chemical clock demonstration experiment to display chemical kinetics in action; it was discovered by Hans Heinrich Landolt in 1886. The iodine clock reaction exists in several variations, which each involve iodine species (iodide ion, free iodine, or iodate ion) and redox reagents in the presence of starch.Two …
