Description

The Briggs-Rauscher reaction is a prototype of an oscillating reaction. An oscillating reaction fluctuates between different states. In the Briggs-Rauscher reaction, the solution is initially colorless or slightly yellow and later turns deep blue. The blue color is due to the iodine-starch complex, which is formed by iodide ions. As soon as these ions disappear during the complex reaction cycle, the solution becomes colorless again. In the experiment, the Briggs-Rauscher reaction is built up and followed.
