Abstract
The ferricyanide–sulphite reaction has been shown to proceed via the intermediates [Fe(CN)5(CNSO3)]5– and [Fe(CN)5(CNSO3)]4–, followed by hydrolysis of the latter to ferrocyanide and sulphate. In the presence of catalysts such as animal charcoal and Cu++ aq ions, there is a reduction in the amount of intermediate formed, and radioactive tracer experiments indicate the formation of appreciable quantities of dithionate ion.Keywords
