  • Chemical Laboratories, Govt Science College, Rewa Manuscript received 11 February 1980, revised 20 December 1982, accepted 1July 1983 The oxidation of D-galactose, D-xylose and L-arabinose by chromium peroxydi­chromate has been studied in very dilute sulphuric acid (0.12-0.066 N). The reaction is of first order each in substrate, oxidant and sulphuric acid. HCrO\(_4^-\) ion appears to be the predominant oxidant. Neutral salts and Mn(II) have retarding effect on the reaction. A mechanism which is consistent with the observed rate laws and experi­mental facts has been proposed.
