Abstract: A new volumetric method for monitoring the oscillating Belousov—Zhabotinsky reaction with oxalic acid is described. While an oscillatory behavior in the potential of the Pt redox electrode at slow stirring without inert gas bubbling can be observed, a monotonous, nonoscillatory course was found both at the slow and rapid stirring rates for the carbon dioxide evolution. Possible reasons for such observations are discussed.
