The reaction of ascorbate with chlorite has been difficult to study due to the formation of reactive species that also react with the ascorbate.  In this reaction, hypochlorite forms as a byproduct. To prevent the reaction of hypochlorite with ascorbate DMSO was used to scavenge the hypochlorite formed. Reaction rates were measured for varying chlorite and ascorbate concentrations using excess chlorite, 25�C, and 0.1M ionic strength. The rate law was found to be first order with respect to both ascorbate and chlorite.  The activation energy of the reaction was also obtained using an Arrhenius plot.
