Abstract—Studies on the oscillatory behavior of resorcinol with different catalysts, different co-ions for the same catalyst (acetate, carbonate, sulphate) and different media give different trends. The use of different catalysts shows that Mn(II) is most reactive and Ferroin is least reactive with respect to resorcinol with respect to different oscillatory parameters like time period and induction period. The use of different acidic media clearly shows the ease with which protonated species is formed in sulfuric acid and hence maximum number of oscillations is seen in this medium as compared to orthophosphoric acid where no oscillations are seen. Study on the different co-ions is carried out for the first time and it is observed that co-ions also have a good impact on nature of oscillations. Such ions can be treated as co-substrates although oscillations are not observed while using such compound separately with the bromate (i.e. in absence of resorcinol).
