Quantitative substantiation of the difference in the intermediate stages of dehydro-L-ascorbic acid polarographic reduction to L-ascorbic acid and of L-ascorbic acid polarographic oxidation to dehydro-L-ascorbic acid is given. It has been established that the first process is described by the CrEqrCi mechanism with the preceding reversible and the following irreversible rate determining chemical stages and with the quasi-reversible transfer of the first electron in two parallel stages with and without participation of proton.
