## Abstract At pH ca. 4 the rate of oxidation of ascorbic acid and of phenylhydroxytetronic acid by nitrous acid in the presence of excess nitrite ions is found to be independent of reductone concentration. The rate law is k~2~ was evaluated both in water and in aqueous dioxan. Under the same cond

## Abstract Addition of azide ions considerably slows down the oxidation of ascorbic acid by nitrous acid. At a pH of about 2 an approximately 10 fold excess of hydrazoic acid over ascorbic acid changes the rate law found in part III into This is identical with the rate law found in 0·1 to 0·5 M a
