Abstract:
Complex periodic oscillations which are associated with Farey sequences and sustained aperiodic oscillations (maybe chemical chaos) have been first observed in Hydrogen Peroxide-Potassium Thiocyanate-Cupric Sulfate System in a CSTR. When pH is high (generally at pH>9), oscillations in pH and Pt potential in solution are synchronous, and pH increases as Pt potential in solution increases; when pH is low (gernerally pH<9),oscillations in pH and Pt potential are antiphase. Birthymicity of two oscillations appears at a same condition. A sample explanation is discussed.
Key words: Nonlinear chemical reaction, CSTR, Complex oscillations, Birhythmicity
