Oscillation reactions of Belousov-Zhabotinskii type with hydroxy acids in closed systems without removal of bromine

Abstract

Hydroxy acids such as tartaric, mandelic, lactic, and glycolic acids generate chemical oscillations in Belousov-Zhabotinskii reactions even in closed systems if the solution is not bubbled with an inert gas. Reduction of Ce(IV) ions with hydroxy acids is accelerated by bromine, whose reaction with them is sensitive to illumination.
