Hi!
I've been looking for the Standard Reduction Potential for IO₃^-  IO₄^-. I have a Handbook and it's not there, also I've looked in some Inorganic Chem and google, with no luck.

It's for the Rx:

KIO₃ + K₂S₂O₈ + 2KOH KIO₄ + 2K₂SO₄ + H₂O

If anyone has any idea where to find it or if it has been calculated, please tell me!
Thanks!

I don't have access to this paper, but if you can find someone who does it might help. http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6TG0-49DF832-1&_user=10&_coverDate=11%2F15%2F2003&_rdoc=1&_fmt=high&_orig=search&_sort=d&_docanchor=&view=c&_searchStrId=1360597434&_rerunOrigin=google&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=2c83819a765c6bad1ab4dbf9b9439f4f

I don't have access either =/... Thanks anyway!

All I have is

H₅IO₆ + H⁺ + 2e^- -> IO₃^- + 3H₂O

V = +1.6

IO4- + 2H+ + 2e- <--> IO3- + H2O
