Kinetic studies of the oxidation of L-ascorbic acid by tris(oxalate)cobaltate in the presence of CDTA metal ion complexes
It was investigated the kinetic of the reduction reaction of tris(oxalate)cobaltate by L-ascorbic acid, H2A, at different acidity. The Co(III) complex was monitored at 600 nm, under pseudo-first-order conditions: [H2A] = 3.0 x 10-2 mol L-1, [Co(C2O4)3]3- = 3.0 x 10-3 mol L-1, in the presence of CDTA...
