The iodine clock reaction is a classic chemical demonstration in which the appearance of a blue-black color indicates a sudden change in reaction conditions, typically due to the production of iodine-starch complexes. This reaction is commonly used to illustrate chemical kinetics and the principles of reaction rates in educational settings.
