Abstract: | The effects of various salts on the kinetics of ferrocyanide oxidation by periodate are reported. The reaction exhibits salt effects of low specificity at low concentrations of the added salts (<0.1 M). At higher concentrations, the effectiveness order for alkaline cations is Li+>K+>Na+ and tetralkylammonium ions have a comparable (Et4N+) or even greater (Me4N+) accelerating effects than alkaline cations.
