## Abstract The kinetics of the permanganateβsulfite redox reaction has been studied in the alkaline medium using a stoppedβflow technique. In the pH range 10 to 12 the reaction was found to obey the rate expression: βΒ½__d__[MnO~4~^β^]/__dt__ = (__k__~1~ + __k__~2~[OH^β^]) [MnO~4~^β^] [SO~3~^2β^].
The influence of pH, oxygen partial pressure, and sulfite conversion on the reaction rate of uncatalyzed sodium sulfite oxidation is determined experimentally at a temperature of 20Β°C. In addition to these experiments, the change in composition of the sulfite solutions during the reaction was estima
The kinetics of the heterogenous oxidation of aqueous solutions of ammonium sulfite with oxygen transferring from the gas phase was investigated. Experimental data in the form of rate of oxygen uptake were obtained by utilizing a stirred cell. Results obtained from the cobalt catalyzed system were a
