🧠 on Instagram: "The iodine clock reaction, discovered by Hans Heinrich Landolt in 1886, is a classic experiment that vividly demonstrates chemical kinetics. It involves a sudden color change from colorless to blue, illustrating the concept of reaction rates. This reaction occurs when two clear solutions are mixed, with one stage of the reaction taking longer, leading to a delayed color change. Widely used in classrooms, the iodine clock reaction offers a hands-on way to explore the factors inf
