The video explains reversible chemical reactions using an oscillating clock reaction experiment. It involves three chemical solutions and a magnetic stirrer to demonstrate color changes in a beaker. The experiment showcases a sequence of reactions that produce iodide ions, iodine molecules, and color changes from amber to dark blue to colorless. The reaction continues until the reactants are consumed, leaving a dark blue liquid. This is known as the Briggs Rauscher oscillating reaction.
