A new experimental method using an electrochemical technique is presented for the study of the oxidation kinetics of water and organic compounds. The electrogeneration of silver (II) in 6 M nitric acid is presented. Good agreement is found between a theoretical model and the experimental results. Since the Ag(II)/Ag(I) system obeys Nernst’s law, the potential of this couple can be followed as a function of time. This technique has been used to study the oxidation kinetics of water, formic acid, acetic acid, and urea by silver (II) in 6 M nitric acid. The reactions were found to be first order with respect to organic compounds. Oxidation kinetics of formic acid and acetic acid showed first order in silver (II) and that of urea was found to be second order in silver (II).
