Abstract
Stationary mosaic patterns may spontaneously develop in a thin film of solution containing H2SO4, NaBrO3, KBr, ferroin, and 4‐cyclohexene‐1,2‐dicarboxylic acid. The pattern formation is affected by initial reactant concentrations and depends on the generation of elemental bromine. Depending on initial reactant concentrations, a vivid nonsynchronous oxidation transition may also occur. Results of experiments designed to distinguish between physical and chemical mechanisms are presented.Keywords
