Our results are in. accordance with the results in the celebrated works [18, 19] on chemical reaction os- The first known homogeneous oscillating chemical reaction, reported by W. C. Bray in 1921, was between hydrogen peroxide (H2O2) and iodate (IO 3) in acidic solution. Because of experimental difficulty, it attracted little attention and was unsuitable as a demonstration. In 1958 Boris Pavlovich Belousov discovered the Belousov–Zhabotinsky reaction (BZ reaction). The BZ reaction is suitable as a demonstration, but it too met with skepticism, largely because such oscillatory behaviour w…

The results in this direction sometimes WebMar 1, 1989 · The field of oscillating chemical reactions has grown dramatically over the last 15 years. The reasons for this activity are the intrinsic chemical interest in the behavior and mechanisms of oscillating chemical reactions and the connection between oscillating reactions and the properties of nonlinear differential equations.
http://scienceline.ucsb.edu/getkey.php?key=116 A chemical oscillator is a complex mixture of reacting chemical compounds in which the concentration of one or more components exhibits periodic changes. They are a class of reactions that serve as an example of non-equilibrium thermodynamics with far-from-equilibrium behavior. The … See more The earliest scientific evidence that such reactions can oscillate was met with extreme scepticism. In 1828, G.T. Fechner published a report of oscillations in a chemical system. He described an electrochemical cell … See more Chemical systems cannot oscillate about a position of final equilibrium because such an oscillation would violate the second law of thermodynamics. For a thermodynamic system which is not at equilibrium, this law requires that the system approach equilibrium and not … See more • Catalytic oscillator • Mercury beating heart • Blue bottle experiment • Clock reactions See more Belousov–Zhabotinsky (BZ) reaction A Belousov–Zhabotinsky reaction is one of several oscillating chemical systems, whose common element is the inclusion of bromine and … See more • Video of BZ reaction • History of oscillating reactions See more
