Iodine clocks
WebIodine Clock Reactions. The iodine clock reaction is quite spectacular. In this phenomenon, two colorless solutions combine into another clear solution. Then, almost spontaneously it turns into a deep-blue color. It is very mysterious. In this reaction, a strong oxidizer reacts with a strong reducing agent.
