The kinetics of oxidation of L-ascorbic acid (H2A) by the mononuclear complex [Co(NH3)5(OH2)] (C103) 3 have been studied spectrophotometrically at 490nm. The mechanism involves single one-electron transfers involving the pentaamminehydroxo complex and the ascorbate anions (HA-and A 2 ), subsequent f

## Abstract Ascorbic acid is not oxidized (thermally) by ferric salts in oxalic acid solution. When ferric salts in oxalic acid solution are irradiated in an atmosphere of nitrogen, ferrous ions are produced; in an atmosphere of air, ferrous ions are produced when the ratio of iron to oxalate excee
## Abstract The inhibition of browning of ascorbic acidβglycine mixtures by bisulphite ion has been studied at pH 3.0. Glycine enhances the formation of coloured products from ascorbic acid but it is not involved in the stages leading to the formation of 3βdeoxyβpentosulose as a reactive intermedia
