WebBray-Liebhafsky Reaction Hi, I am a student studying the effects of varying concentrations of hydrogen peroxide and sulfuric acid on the Bray-Liebhafsky oscillatory reaction. The problem is that there is no literature with explanations for the effects of changing these reactants on the induction period and amplitude.

WebThe Bray–Liebhafsky reaction is a chemical clock first described by William C. Bray in 1921 and the first oscillating reaction in a stirred homogeneous solution. He investigated the role of the iodate (IO−3), the anion of iodic acid, in the catalytic conversion of hydrogen peroxide to oxygen and water by the iodate. WebJun 1, 2024 · Landolt's iodine clock reaction between sulfite and excess iodate is the most popular example [16,17]. Belousov–Zhabotinsky (Malonic acid oxidation) [18], Bray–Liebhafsky (iodine-iodate with H 2 O 2) [[19], [20], [21]], and Briggs–Rauscher (iodine clock) [[22], [23], [24]] also reported clock reactions. These inorganic-based clock ...
