Abstract

Oxidants such as Ce(IV) and MnO4 - in 1N H2SO4, or Fe(lll) in 1M HCI, will oxidize silver from a rotating platinum electrode. By depositing known amounts of silver upon the electrode and determining the time variation of potential of the electrode, the time required to oxidize the silver can be determined. This time is inversely proportional to the concentration of oxidant in solution. The lower limits of applicability were Ce(IV) 10-6M, MnO4- 5 × 107M, and Fe-3 2×10 -6 M. The oxidation of silver metal by these oxidants was found to be mass transfer-controlled.
