Abstract: The oscillatory behaviour of isomers of hydroxybenzoic acid has been studied in 1.0 M H₂SO₄ with and without methyl ketones as mixed substrates. The presence of Br⁻ and the critical bromide ion concentration have been found to have a key role in the present study. Moreover, the effect of ketones such as acetone, butanone and pentanone has also been found to affect the oscillatory characteristics such as induction period, time period, frequency and number of oscillations. The oscillations arise in such systems provided the inhibitory reaction and autocatalysis balance each other.
