Effect of Different Counterions of the Manganese Salt as Catalyst on the Kinetics of Resorcinol-Based Belousov-Zhabotinsky Reaction.

ABSTRACT Kinetic studies on the Belousov-Zhabotinsky (BZ) system with various metal ions as catalysts have been carried out for a long time, but the effect of counteranions associated with the metal ion solution used as the catalyst in the BZ reaction has not been explored. Thus, we have chosen some metal salts as catalysts having the metal ion (Mn n+) but with various anions to study the role of different anionic moieties of catalyst on the oscillatory behavior of the resorcinol-based BZ reaction system. It is found that organic-type anionic moieties marginalize the role of organic substrates in the reaction system. On the other hand, the inorganic counterions of the catalyst show salting out effects, thereby increasing the ionic strength, which affects the mobility (diffusion) of the ions in our system performed under batch conditions.
