Popis:	The oxidation of ascorbic acid by aqueous copper(II) has been studied under anaerobic conditions with [Cu 2+ ] in the range (1-5)×10 −3 M, total ascorbic acid concentration of 5×10 −5 M, and [H + ] of (0.50-10)×10 −3 M NaClO 4 /HClO 4 at 25 o C. The kinetic effect of the chloride ion concentration also has been investigated. The observed pseudo-first-order rate constant. The resualts are discussed in terms of the probable mechanisms for the direct and chloride-catalyzed paths for the oxidation, and earlier results in the presence of acetate are reanalyzed
