Abstract

In non-buffered aqueous solutions, ascorbic acid is oxidized by o-iodosobenzoic acid according to a second-order reactio: expressed by the differential equation:-d [AA]/dt= kz [AA][o-RIO]. over the PH range 4 to 8 (half-life of 13 hours for 0.001 M solutions). The reaction exhibits general acid catalysis in agreement with the assumption that o- iodosobenzoic acid and the acid catalyst combine reversibly through hydrogen bonding to ...
