Abstract:

This paper presents a study of the concentration range of reactant of oscillation reaction in α-hydroxy-propionic acid-KBrO3-MnSO4-H2SO4-propanone system. The special feature of the reaction is a damped oscillation. A section of the damped oscillation wave is similar to a spindle. Effects of many factors on the oscillation have been examined. The period and amplitude as function of the initial concentration of each reactant have been studied. It was found that mumbers, period and amplitude of each section of damped oscillation and preoscillatory time depend on the initial concentrations of the reactants.

Key words: α-hydroxy-propionic Acid, Chemical oscillation, Preoscillatory time, Oscillation period
