oscillating chemical reactions

Oscillating chemical reactions are dynamic processes where the concentrations of reactants and products change periodically over time, creating a noticeable fluctuation, like a chemical "heartbeat." A well-known example is the Belousov-Zhabotinsky reaction, where the colors of the solution shift back and forth due to the interaction of specific chemicals. These reactions occur due to feedback mechanisms within the chemical system, allowing reactants to be consumed and regenerated repeatedly. They illustrate the complexity of chemical kinetics and can be observed visually, making them fascinating both scientifically and aesthetically.
