## Abstract Ascorbic acid at a concentration of 10^β3^ M was a more effective proβoxidant in the presence of low copper concentrations than at high concentrations, particularly in the initial stages of oxidation or in the lower pH range (5Β·5β4Β·7). This suggested a much more complex role for ascorbi
The pertechnetate ion oxidizes ascorbic acid in strong acid medium to form red species. A reaction mechanism has been developed which correctly predicts all the experimental facts. The results obtained support the postulate according to which the red species corresponds to a complex formed between T
