Balancing redox equation
« on: January 30, 2016, 07:39:22 PM »
How do you balance this equation?

IO3{-} + I{-} + H{+} = I3{-} + H2O

I tried using oxidation numbers but there seems to only be reduction?

What do you consider to be the reduction?

Do you think there might be an oxidation going on as well?
Or you could, you know, Google it.

reduction: IO3- --> I3-
the oxidation number for I goes from +5 to -1

sorry, I can't seem to see any oxidation reaction

***edit: I think I figured it out, thanks!***

Did you? Nice!

Mind showing us what you did (at least the first couple steps)?
Or you could, you know, Google it.

Oxidation number of iodine in I3- is not equal to -1

One more hint:
Check what is I3-. Divide this molecule fpr easier calculation.
