Title: Oxidation of dithionite to dithionate?
Post by: AberdeenBill on December 20, 2016, 09:17:56 AM

Hi all,

Does anybody have a reference (journal article or textbook) that describes the oxidation of dithionite ions (S₂O₄^2-) to dithionate ions (S₂O₆^2-).  I can't find anything in the usual sources such as Greenwood and Earnshaw.
 
Many thanks,
Bill

Look at structure of Acid Blue 317 and calculate oxidation number through analogy.
