The Belousov-Zhabotinsky reaction is typically carried out in a petri dish or beaker. The reaction mixture contains a substrate, such as malonic acid, an oxidizing agent, such as potassium bromate, and a catalyst, such as cerium ions. When the reaction is initiated, the substrate is oxidized, which produces a free radical. This free radical then reacts with the oxidizing agent, which produces another free radical. This process continues in a chain reaction, which leads to the production of oscillations in the concentration of the free radicals and other components of the reaction mixture.

The oscillations in the Belousov-Zhabotinsky reaction can be visualized by adding a color indicator to the reaction mixture. The color indicator will change color depending on the concentration of the free radicals in the reaction mixture. This allows for the visualization of the oscillations in the reaction mixture.

The Belousov-Zhabotinsky reaction is a powerful tool for demonstrating oscillations and patterns in a chemical system. This reaction has been used to study the behavior of complex systems, such as biological systems. The reaction is also a valuable tool for teaching about the principles of chemical reactions and oscillations.
