Monitoring the Formation of Oxygen Bubble Patterns as a Forecast for Reaction Dynamics

Abstract

A non-equilibrium process, i.e., the state I (low concentration of iodide and iodine) to the state II (high concentration of iodide and iodine) transition, occurring after oscillatory Briggs-Rauscher reaction, was monitored by fast camera. The experiment's goal was not only to monitor the release of oxygen and the phase transition but also to use patterns formed by oxygen bubbles to get new insight into the kinetics of the process and the formation of solid iodine. To the best of our knowledge, it is the first time that an oxygen bubble pattern obtained by a fast camera has been used to analyze oscillatory system dynamics.
