The Briggs-Rauscher reaction, also known as 'the oscillating clock', is one of the most common demonstrations of a chemical oscillator reaction. 🕒 Our University of Sydney chemists demonstrate what happens when three different colourless solutions are mixed together to give one solution. 🧪 This particular solution contains (among other thing) potassium iodate, starch, hydrogen peroxide and a strong acid.💫 The solution changes between colourless, amber and dark blue as a result of several comp
