Abstract: 
Upgraded design of the experimental setup for monitoring Bray-Liebhafsky (BL) oscillatory reaction dynamics allowed simultaneous recording of platinum electrode potential and gaseous pressure changes over time. Experiments were performed at two stirring rates (600 rpm and 1200 rpm) in five replicates. Evolved gas at two mixing rates is correlated with reaction induction period, number of oscillations, period between oscillations, oscillation amplitude and number of produced oxygen moles per oscillation. Obtained trends indicate that the amount of formed gas facilitates initiation of iodine oxidation. Results are in agreement with previous findings which point to the importance of heterogeneous effects in reaction of iodine oxidation.
