Abstract

Non-Br-controlled Belousov-Zhabotinskii oscillators have been studied. Not only are Br oscillations suppressed but redox potential oscillations are also subsequently suppressed on addition of sufficient Ag+. Analytical studies show that there is still sufficient BrO3 in the systems at this instant. The redox potential oscillations are revived on addition of BrO3 but not on addition of organic substrate. The phenomenon is general and has been observed in systems having (a) malonic acid+Ce4+, (b) phenol and (c) oxalic acid+acetone/cyclohexone+Ce4+.
