The reactions of iodate and periodate with Fe(phen) 3 2+ have been studied in neutral medium iodate ion is unreactive with ferroin in aqueous solution. The reaction is autocatalytic in the case of IO 4 − . The autocatalysis disappears in an excess of IO 3 − . The rate constants of both processes were determined and a reaction mechanism has been proposed. © 1996 John Wiley & Sons, Inc.
