I. Rao et al., KINETICS AND MECHANISM OF SILVER(I)-CATALYZED OXIDATION OF MALONIC-ACID BY PEROXODIPHOSPHATE IN ACETATE BUFFERS, Transition metal chemistry, 18(4), 1993, pp. 409-412
The kinetics of the silver(I)-catalysed oxidation of malonic acid by p
eroxodiphosphate (pdp) was studied in acetate buffers. The rate law as
represented by - d[pdp]/dt = [H+]2+k2[H+]+k3K3)/([H+]2/K2+[H+]+K3)}[p
dp][Ag(I)] conforms to the proposed mechanism. The rate is independent
of malonic acid concentrations. Acetate ions do not affect the rate:
however, the rate decreases as the ionic strength increases. A probabl
e portrait of reaction events is suggested. A comparative analysis of
the reactivity pattern of malonic acid towards peroxodiphosphate and p
eroxodisulphate in presence of silver(I) has been made.
