The "Briggs-Rauscher reaction," often misremembered as the "Brigg Rouche reaction," is a famous chemical demonstration known as the Briggs-Rauscher Oscillating Clock Reaction, where a solution cycles through colorless, amber, and dark blue, demonstrating complex non-equilibrium chemistry. Discovered by Thomas Briggs and Warren Rauscher in 1972, it involves iodine, malonic acid, hydrogen peroxide, and starch, creating visible oscillations as different reactions temporarily dominate, showcasing pe

The Briggs-Rauscher reaction is a striking oscillating chemical reaction known for its rhythmic color changes between clear, amber, and deep blue. This reaction involves potassium iodate, hydrogen peroxide, and malonic acid, with manganese sulfate as a catalyst and starch as an indicator. In cycles, iodine is produced and consumed, causing color shifts: clear when iodine forms, amber as it reacts with malonic acid, and deep blue when iodide ions complex with starch. The reaction continues these
