Oscillatory Reaction of Bromate-Gallic acid. A Calorimetric and Electrometric Study in Aquo-Organic Solvent Media
-
S. Biswas
The oscillatory reaction between potassium bromate and gallic acid (in presence of sulfuric acid and ferroin indicator) has been calorimetrically and potentiometrically studied in binary mixtures of water and organic solvents viz. dimethyl formamide, acetonitrile, tetrahydrofuran and 1,4-dioxan. The effects of solvent polarity, stirring condition, indicator concentration, aerial oxygen and chloride ion on the oscillatory process have been examined. The oscillatory behaviour of the reaction probed by the potentiometric method has a general agreement with the calorimetric method. An attempt has been made to determine the order of the Fe2+→Fe3+ oxidation reaction. The damping coefficients of the oscillatory process in aqueous and mixed solvent media have been estimated.
